I have cell BOB. BOB sums A1:A25. I want to be able to click on

a macro that will find BOB then change its formula so it sums A1:A26.

It will +1 cell to the end (A27, then A28, then A29) of the sum range

each time I click the macro. How can I do this?

The sum is more of an example. Its not just suming. There's 3

formulas with cell names:

=NPV(G63/12,$D$112:$D$183) (bob)

=SUM(C25:C111) (dan)

=SUM(D112:D183) (jim)

I need everymonth to be able to hit this macro so it moves the

reference cell up one. So next month I will hit the macro and get

the formulas

=NPV(G63/12,$D$113:$D$183)

=SUM(C25:C112)

=SUM(D113:D183)

In bob, the D112 becomes 113, in Dan, C111 becomes 112, and in Jim

D112 becomes 113. It all basically moved the formulas one cell down.

Not trying to be obstrepelous but if it's a question of only 1 cell a month

what about setting things up for 12 months and writing stuff to the cells as

the data comes in.

I realy feel that if you could write a formula rather than code for a

solution you'd be better off.

What about using COUNTIF?

I'm not a statistician really so I'm not sure how this would affect NVP but

the SUM formulas would be fine.

The problem with expanding the formuals with VBA is picking up the current

range to be expanded. Writing a formula to a cell is simple.

With string manipulation it wouldn't be too tricky tho as long as the target

cell is static so you could put a user function in there.

Are there any empty cells in the range to be SUMed NVPeed?

Its more a matter of going into 3 cells' formulas per sheet for

about 100 sheets per month and the three cells aren't all in the

same place so I have to go to each sheet and look for it, scrolling

up and down in some very BIG sheets and update the formulas each

month which is a time drain. If I could go to each sheet, hit a hot

key, then move on it would speed things up considerably. I don't

know of a formula solution for this. Its not a hard thing to do

every month just tedious and inefficiently time consuming. If you

know of a formula solution, I would love to try it.

For now I have this for VBE script:

if I've misunderstood what you are trying to do - but have you

considered using Offset in your formula?

I'm not too familar with offset. I'm just learning vbe on the fly as

I go here :) I've done this for the "sum" bit and it works but I'm

not sure how to get it to works but its clunky (but maybe that's my

built in error checking). If you can improve upon it with offset

that would be marvelous!:

Yes, Offset should do it. You can store the amount of offset in a

cell somewhere so it will be saved with the file.

You can also look at using CurrentRegion e.g.:

Range("BOB").CurrentRegion.Select

This expands the range to include all adjacent non-blank cells, so

only works if your range is surrounded by blanks cells.

I agree with the other responses that wonder what you're trying to do, but ...

You can get at cell BOB as before:

Range("BOB")

Its formula is available through its .Formula property or its .FormulaR1C1

property. Both give you the formula as a text string - just in different

formats. Work out which one you prefer to use.

You will need to split the formula string into its component parts. Presumably

the formula is

=Sum(A1:A25)

You'll need to separate out the 25 and make it 26, then put it all back together

and assign it to the .Formula or .FormulaR1C1 property of BOB.

Are you sure this is what you want. It isn't moving the formulas one cell down.

It is lengthening DAN and shortening BOB and JIM. This is not the same thing at

all and is also harder to do.

If you simply want to move the formula once cell down - i.e. C25:C111 becomes

C26:C112, then you could offset your original formula by an amount, using the

Offset range function (see the help for information on this).

There is a non-VBA of doing this that might be more appropriate. E.g., I have a

column of numbers in Column A from 1 down, and in E8 I have the row number that

is to be the bottom of my sum. Then:

=SUM(INDIRECT("A1:A"&E8))

Or, for your three - assuming E8 has 112 in it:

=NPV(G63/12,INDIRECT("$D$" & E16 & ":$D$183"))

=SUM(INDIRECT("C25:C" & (E16 - 1)))

=SUM(INDIRECT("D" & E16 & ":D183"))

Any reason why your first formula has $ anchors on the range while the third

does not (with an identical range)?

That is exactly what I want. I want C25:c111 ot become c25:c112 so

it lengthens the range of the formula. It should not just move the

range down one. The other two require the range to shorten.

Actually I think you've brilliantly simplified this script for me. I

didn't think of using indirect. Is there a way to script for excel

to follow these steps?

Find green cell

Return row number of green cell as value in cell A1.

What I want is to color the cell that these formulas depend on

green. Move the green cell down one every month and have the cell A1

read this and return the new row # automatically as a value. Then I

can use the indirect formula to cause all other formulas to auto

update.

If you want to find a cell by colour, you can certainly do so. From memory, you

need the Interior property of the cell, and probably the PatternColor property

of that ...

Range("a1").Interior.PatternColor

However, you're better using other information to tell you where the green cell

should be, and then make it green.

Normally, I'd use conditional formatting for conditional colouring like this.
