We have excel schedules that are linked to our drawings. If we don't open the excel file (first) that these schedules were created in we get bombarded with errors when we open up the drawing. Run-Time Error '91' Object Variable or With Block Variable not set any ideas on how to fix this problem? It is a real pain if you don't open the excel file first, because if you have 10 schedules linked in the drawing you will have to hit "End" or "Debug" 10 different times before the autocad drawing will open up.
