Hi,

=SUM(B1:B6)
If a sum formula like the above returns 0 then the chances are it's trying
to sum text

If you have one of your numbers you are trying to sum in (say) B1 try this
=ISNUMBER(B1)
If it's really a number it will return TRUE or FALSE for text

May be you could post your sum formula or the formula you are trying to sum
the result of.
