I need to write a macro that will perform an operation on every cell on the page -- but only those in th earea I've worked in. The one I've written now goes through all 65,000x65,000 cells which I most definitely DON'T want to do! This is the loop I've currently written -- how do I qualify it to stay within the active range?

(btw--the range is variable, so I can't do something like
For Each cell In Range(Cells(1, 1), Cells(20, 10)


Current loop
For Each cell In Cell
...
next cel

Thank you so much!
