We have built a macro driven template/workbook where different people enter data and proceed through the tabs by hitting the 'next' button. Behind the button is a macro that takes them to the appropriate spreadsheet to enter additional data. Some, but not all, users get the VB error "VB runtime error 2147024809" 80070057 specified value out of range. 1) what causes this error and 2) why is not consistent across all machines. All people are using EXCEL 2007. Help!
