A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
In VBA, go to the Tools menu, choose Options, and then the General tab. There, change the error handling option to "Break In Class Module". This will cause the debugger to take you to the line that is causing the error within the class, rather than the line that instantiated the class. You should always use this option. I can't think of any reason to do otherwise.
