Hi
I have a column where I have a numbers more than 0, numbers less than 0, 0's
and blanks. I would like to put in the formula in the query to calculate
those numbers, but only for items more or less than 0, for those that are 0
or blanks I need to put 0 in the formula. I tried <>0, but it doesn't catch
blanks.
Can you help?

To handle 'blanks' you should use the Nz() function

Nz(YourFieldName, 0)

This will automatically return a value = 0 when the field is Null. Once
this is inplace, you should be able to perform your calculations.

If you require further assitance, please explain your problem further. What
do you need to calculate?

Hi
Thank you for your replay. I tried NZ and it didn't work, but IsNull works
fine, but now I have next problem. I have two columns with numbers but when I
sum these two columns and run a query it prompt always the columns headings.
I don't know why. There are no blanks, all are numerical.
Can you help?

but IsNull works fine,
I think you need to test some more as IsNull returns a zero if it Is Not
Null and a minus one for null.
In design view set fields like this to test --
Test: SomeField Test_For_Null: IsNull([SomeField])
Post your SQL by opening query in design view, click on VIEW - SQL View,
highlight all, copy, and paste in a post.
Someone can check it for you.
