Run-time error '57121': Application-defined or object-defined error
Posted on 2010-09-07
I have an Excel file that people in the company access one at a time (the file is NOT set to "Share Workbook.")
And after some VBA and file structure changes, this error is sporadically occurring after they click enable macros.
After this error appears, I see that a control button I've inserted is deleted, none of the VBA code will run (although the code exists in the editor), and all data validation drop down lists are wiped out!
I cannot duplicate this error on my PC, but it is happening, seemingly sporadically, across computers. It's happened 4 times today and I need to constantly restore the file.
I need help, and fast!
