I have a spreadsheet that has several cells that have links to a cell located
in a different, (i.e. ='Sheet 3'!AC8). The cell on the different sheet calls
a user defined function. When I'm in the first sheet and save the file,
those cells that link back to sheet 3 go to zeroes. If I display sheet 3 and
then redisplay sheet 1, the cells will contain the correct values, otherwise
they will contain zeroes. My UDF called from sheet 3, has
Application.Volatile, all Office and OS maint is up to date. Anybody have
any guesses as to what I'm doing wrong or where to look?
