Can't upload excel spread sheet
I have an Excel spreadsheet that I can upload no problem, but my users cannot. They receive the error: Object reference not set to an instance of an object.
I have checked for hidden rows and columns. The users have not changed any formatting. And when they send me one of their spreadsheets, I get the same message. My CRM Architect is looking into it, but figured I'd ask here. Myself and the user are running the same versions of Excel, and its not a permissions issue in the app we are trying to load to. Any ideas would be most appreciated.
