They are in table cells, but I also tested the find logic on a blank word document with just these four plain text values (no formatting, no table, etc.) and it didn't find any of them:

7.0%
.0%
0.0%
94.0%

It would have been helpful if you'd said so at the outset. On its own, the process won't work in tables. You could, however, use a series of wildcard Find/Replace expressions, where:
Find = .[0-9]%
Replace = ^s^&
Find = ([0-9])^s(.[0-9]%)
Replace = \1\2
This will now leave you with the .0%s with a non-breaking space before them, so you can then do a wildcard Find for just those, with:
Find = ^s.[0-9]%
I tested the [!0-9].[0-9]% wildcard Find expression in an ordinary document before I posted it. It worked then and it still does.

Just wanted to follow up and say both approaches worked and thank you. I didn't point out the table issue because I thought I ruled that out as an issue. For some reason, the [!0-9].[0-9]% wildcard for non-table data didn't work on my PC at work but did work on my PC at home, even though both PCs use Word 2010. Still can't figure out what's causing that.

But thank you again for your help.
