All, thanks, every comment helped. I think the issue of "replace is just not working" is because I was trying to go from round of 8 to rounds of 10 and the symbol I had for rounds of 8 was a modified rounds of 10. So when I was trying to "replace" wiht the rounds of 10, it was staying as that 8?????
Any way I made a new document, placed a round of 10, then went back to the original document and selected all, hit replace and went to that new document to find the round of 10, select, BOOM, done.
