Find/Replace

[jo-]

I'm trying to use the Find/Replace from the tool bar, but the field that I am working with contains nothing. On the FIND WHAT: line, I have tried everything that I have found in the help sections, but nothing works. I have tried NULL, IS NULL, " ", 0, IS BLANK, BLANK. Does anyone have any ideas? Thank you all for this site, and for all your help!!!!!!!
just me jo-
