skip null value in field when calculating

A

Annemarie

I'm trying to calculate the score from survey questions, but don't get an
accurate total if there are null scores. I'm working with over 40,000 surveys
so filling in the null fields to something isn't possible. Is there a formula
I can add to my query that skips the null fields and totals the score(s)
without it?

Thanks

This is what I have:
Expr1:
Nz(([comments_tbl]![Question_1]+[comments_tbl]![Question_2]+[comments_tbl]![Question_3]+[comments_tbl]![Question_4]+[comments_tbl]![Question_5])/5)

and it doesn't work.

comments_tbl is the name of my table the query is pulling the data from
Question_1 - Question_5 is the name of the fields in the table

Try this --
(Nz([comments_tbl].[Question_1],0)+Nz([comments_tbl].[Question_2],0)+Nz([comments_tbl].[Question_3],0)+Nz([comments_tbl]![Question_4],0)+Nz([comments_tbl].[Question_5],0))/5
