I am working with a document library in Sharepoint 2007. In my check-in form, I have a few columns that are linked (1 lookup column &to 3 cascade lookup plus columns). For example, I have column A set to be a LOOKUP. Column B, C, & D are set as a CASCADING LOOKUP PLUS. The problem I am having is when users go to the check-in form (after selecting the document), Column B, C, & D show results for EVERYTHING. Previously, when I set this library up I did not have this issue. Previously, I could select a value for Column A, then Column B, C, & D would filter the results. Right now, before users even select a value for Column A, Column B is showing all the results, which it did not do before. I did find a small workaround, but it's not great. After I select a value for Column A, I click one checkbox wait a few seconds, then all 3 columns filter. Very strange... Anyway, I have spoken with our IT folks, but they were not certain. I believe the restarted IIS for our site one time, and that may have helped, but I can't be certain. All I know is that the issue has come back. Any help would greatly be appreciated...thanks!
