I'm using a subform linked to the main form by a bidder number field. In the subform, I added a group header and put the field LS in it so that it would list all records designated as Live first under a heading that says Live, and then all that are designated as Silent under a heading that says Silent. The subform works beautifully by itself, but when I put it in the main form, I get an error that says "Access can't find the field 'Live or Silent' referred to in your expression." When you click Ok, it displays the error over and over (I'm guessing for each match) until you finally get to the end. All the while I can see the data displayed exactly as I'd like behind the error message, until the last error when it removes it. If I remove the LS Header, or move the field from the LS header into the detail section, it works perfectly, but I don't want Live or Silent listed on each record. I would also note that this works perfectly in Access 2003. It just won't work in Access 2007, even when you convert to Access 2007 format. Any thoughts would be appreciated.
