Thank you for the quick reply macropod.

So I used the Find/Replace function (Ctrl+F), and in the Replace tab, did the following:

. In the Find What field: (global.test_[0-9]{1,})*^13
. Ticked the "Use wildcards" option under Search Options
. In the Replace With field: FTEST(\1)^p
. Clicked Replace All

Unfortunately, I get a message telling me that 0 replacements were made. Am I doing something wrong is there another way to do this?

Thanks!
