I beleive I have found it

=IF(COUNT(K1:K20)=COUNTA(K1:K20)+(COUNTBLANK(K1:K2 0)),"NO","YES")

is there any flaw in this formula, I have tried it with all of the invalid
characters I could thnk of, so far it works

Thanks for all of your help!

Still dosent work with the blanks, I tried this formula, but with the same
result.

=IF(COUNT(K1:K20)+(COUNTBLANK(K1:K20))=COUNTA(K1:K 20)+(COUNTBLANK(K1:K20)),"NO","YES")

=COUNT(AI7:AT7)+SUM(ISBLANK(AI7:AT7))=COUNTA(AI7:A T7)+SUM(ISBLANK(AI7:AT7))

Agan TRUE or FALSE. If you want something else then use it as the test of
an IF() formula.

That is almost what I want, but I need it to treat the blanks the same as
it
treats a space or a coma

=COUNT(AI7:AT7)=COUNTA(AI7:AT7)

which will return TRUE or FALSE doe what you want?

I have a range of cells AI7:AT7 and I need a count to see if users made
an
error by entering a blank, a space, a period ect. Where numbers should
have
been enterd. I have tried several count variations and could not come
up
with
any thing.
