Thank for your help Mario ..   i replied but somehow my answer didn't make it here.  yes i can print a T1 fine and a T183 and so far any schedule but 1 at a time.  as soon as i try to combine more than one document it gives me the error message.  i tried one of your suggestions, below about finding the one form that is the culprit but so far i get only that adding more than one form will mess it up ie it prints the T183 and T1 separately but if i combine them i get an the same error message?
