I decided to work on this report a little more at home, but I ran into a strange error. When I run the report and click the button that starts SortTable, I get an error: "An unhandled exception has occurred in the form's code. System.InvalidOperationException An error occurred in the form's rules or code. The number of rule actions or the number of calls to the OnAfterChange event for a single update in the data exceeded the maximum limit." After clicking OK I have to click OK about 10 or 15 times on "Some rules were not applied, Operation Aborted", it then does the original error again, then completes the sort. The sort button(s) I've created work fine after that. The only difference at home is that I'm running Windows 8. I will try it at work on a couple of machines to confirm its specific to my PC at home. Any other thoughts?
