You replied:
"Format / sheet  / Hide"

I'm really sorry... but could you write a full line for me?
I would not know how to use this.

Should I assume that if you did not answer my other questions, about
1. if once hidden, the subs that need this sheet would still work  and
2. if the calculated values needed in the other sheets  would be well
transfered,

it's because the answer would be yes?
