I managed to get rid of that error. Not too sure what sorted it in the end but what I did was rename the form, then I commented out all the code behind it and ran it. I uncommented out code a bit at a time to see if it would run and just rearranged the order of my code and that seemed to work.
All is fine now. Thanks. On Feb 18, 1:18 pm, nikhil gaitonde <[email protected]> wrote: > Hi, > > Please try to follow the following steps and debug: > 1.
