I teach Access, but it has been years since I used it in a business. I am helping a company convert from 1997 to 2010. The conversion itself wasn't too difficult, and I have solved several small issues, but I have one that stumps me. On a report, instead of the answer to a simple calculation, it prints: #Type! or a very small square. The formula is =[AdPkTot]*fnGet_mLngQtyPacksPerMix(). Both of these items [AdPkTot] and fn...() are used in other formulas in the report that work fine. I do not know where the report is coming from - I assumed it was a query, but I don't know for sure. I viewed the VBA code and it appears to have no errors. (ie No debug messages appeared.):banghead:I have been working on this one issue for 2 days now. The report opens from a form with 3 parameters. When I try to open it switching from design view to preview, (not from the form) it also asks for 3 other parameters, but I don't know where to find them - IF that is the problem.
