RE: [MS_AccessPros] Confusion with use of "Is Null" and :Nz"

Robin,
If the PhoneAH is truly null then I think all you need is:
Phonz: [PhoneAH] + " AH"

Is it possible the field might be a zero-length-string or something you can't see?

Subject: [MS_AccessPros] Confusion with use of "Is Null" and :Nz"

I have been advised about the use of Nz but he code to use has ben supplied.

I have not learned!

This code in a query:

Phonz: IIf([PhoneAH] Is Null,"",([PhoneAH] & " AH"))

still gives AH in cases where I have dirty data.

I Have learned that this is wrong:

Phonz: IIf([PhoneAH] Is Null,"",(Nz[PhoneAH] & " AH"))

Where is the correct place to use the Nz?

Many thanks,

Robin Chapple
