Find & Replace problems... at the end of my thread (ha)

Hey guys. I have Excel 2007. I have a spreadsheet with email addresses in it surrounded by other text. I want to automatically highlight in yellow each row containing the words gmail, yahoo, hotmail and so on.

I CTRL-H then enter the info as you see it in the pic attached. When I click Replace All it says "that function is not valid". It works like a charm for every other word I test it with. It's almost interesting in a head-exploding kind of way.

Any ideas?
