I have a spread sheet that takes entries in columns headed A and B and does addition and subtraction with the data entered. I have 50 or more rows in some of the spread sheets and for some reason, the formulas only work down to row 39. Data entered in rows 40 and above has no effect. All cells above row 40 (1-39) are identical in their format. It's making me crazy. HELLLLPPPP.
Thanks
