Count IF?
 

Excel 2007
I have a simple formula, =sum(F13:F38)
I have added formulas in other cells that when nothing is in the cells, #N/A
appears in some of the cells (F13 to F18) and my above formula will no longer
work. Is there a way to correct this formula to just add up the cells with
numbers?

Count IF?
 

=SUMPRODUCT(--(ISNA(F13:F38)=FALSE),F13:F38)

Try one of these:

=SUMIF(F13:F38,"<1E100")

=SUMIF(F13:F38,"<#N/A")

I don't think that works.

Why wouldn't it work?

Try putting =NA() into one of the cells in the range... the formula
evaluates to #NA, probably because SUMPRODUCT attempts to multiply the #N/A
by 0 for cells containing #N/A, which it cannot do.

Your right. 0 * N/A = N/A. I thought it would be 0.

Try the following array formula:

=SUM(IF(ISNA(F13:F38),FALSE,F13:F38))

Since this is an Array Formula, you *must* press CTRL SHIFT ENTER
rather than just ENTER when you first enter the formula
and whenever you edit it later. If you do this properly,
Excel will display the formula in the Formula Bar enclosed
in curly braces { }. (You do not type the curly braces -
Excel includes them automatically.) The formula will
not work properly if you do not use CTRL SHIFT ENTER. See
http://www.cpearson.com/excel/ArrayFormulas.aspx for lots
more information about array formulas.
