sum true/false

[greg]

Is there anyway of summing a bunch of rows, that contain true and false.
Where true = 1 false = 0.
I tried changing the cell to a number. with true in it. but no luck.
any other ideas?
thanks

Do the cells contain 1's and 0's or True's and False's?

How about just count the trues/falses:

=countif(a1:a10,true)
and
=countif(a1:a10,false)

=sum(a1:a10)
should sum the cells if they really contain 1's and 0's.

Hi

Multiply by 1.
If you have True/False in A1 and down, then enter enter this formula in B1
and copy down:

=A1*1

True will equal 1 and False will equal 0.
