The formula is an array formula. You must press Ctrl+Shift+Enter
rather than just Enter when you edit the formula.

I have been using this formula in a spreadsheet since 2000 in
office 97.
=SUM(IF(F2:F50="RL",IF(G2:G500,1,0))). It still works until I
try to
modify it. For example change the "RL" to "V". As soon as I
try to
change it it gives me an error. Are there any settings I need
to
change to allow this function to work and be modifies?
