I do a lot of VB programming in the modules, which take data from a
spreadsheet, perform a calcualtion and write the answer back to the
spreadsheet. I have a lot of code in a number of modules. At a certain
point, when I add code to a module, it stops working. Moving the code to
another module ususally corrects the problem.

My question: Is there a limit on the number or size of each module?
