first of all i would thank all of you for that team work :)

Second i change my code  to what you sent to me ... it's worked in
compiling, BUT the result NOT GOOD, the code only applay to drop  down
464 and not applied for dropdown  9, in other word it apply only for
the second part  of the code for dropdown 464 , and if i change the
second part to be dropdown 9 , it will work for dropdown 9 only and
ignore the dropdwon in the first part, i hope that i explained the
issue very well.
