Problem Adding in Build

[ProgEval]

In a query I am adding four fields together in a new field. I am doing the calculation in build. It looks like this...

NewField: Field1 + Field2 + Field3 + Field4

This works fine as long as a have a number entered into every field. Although, if one field is blank, it does not add the others together.

What do I need to do to get it to add the fields even if one or more have a null value?

Thanks!

I figured it out.

NewField: nz(Field1) + nz(Field2) + nz(Field3) + nz(Field4)

I always attempt to be more explicit:
NewField: nz(Field1[red],0[/red]) + nz(Field2[red],0[/red]) + nz(Field3[red],0[/red]) + nz(Field4[red],0[/red])

It also raises a red flag when values (possibly including nulls) are summed across fields rather than across records.
