Query Returns Empty field when adding

[kholm]

When using a query to merge three fields and to come up with a sum i.e. IIF([A]=0,0,[A]++[C]), it return nothing. When I add B and C, I get the correct product, but add in that A, which usually is empty, I get an empty cell.

IIF([A]=0,0,Nz([A])+Nz()+Nz([C]))

You have to make sure you have something in the field in order to add it up for you. To do that, do this in your query

IIf([A]is null, 0, [A])

What this dose is it looks at the field and if it is null puts a 0 there.

It worked

I don't know why, but it worked. What are the Nz's for? Thank you
