I have a user who is trying to add a number of different cells toghehter.
Sometimes they have a value and sometimes they are blank. The formula is
evulating to #Value!.

This is the formula:
I16+K16+M16+O16+Q16+S16+U16+W16+Y16+AA16+AC16+AE16

I tried changing it to this:
(IF(ISBLANK(I18), 0, I18))+ IF(ISBLANK(K18), 0, K18)+ IF(ISBLANK(M18), 0,
M18)+ IF(ISBLANK(O18), 0, O18)+ IF(ISBLANK(Q18), 0, Q18)+ IF(ISBLANK(S18), 0,
S18)+ IF(ISBLANK(U18), 0, U18)+ IF(ISBLANK(W18), 0, W18)+ IF(ISBLANK(Y18), 0,
Y18)+ IF(ISBLANK(AA18), 0, AA18)+ IF(ISBLANK(AC18), 0, AC18)+
IF(ISBLANK(AE18), 0, AE18)

I am still getting the error. What am I doing wrong?
