Hi again,

I have a set of three cascading combo boxes for the following;

Supplier Code, Doc Number, Revision

all is working great, but what I'd like to do is allow the Doc Number combo
to show data for all suppliers if the Supplier Code combo is left empty. At
the moment it shows as a blank if no supplier is selected.

Any help would be great!
Marc

Use a criterion

[Supplier Code] = Forms!yourform!comboboxname OR Forms!yourform!comboboxname
IS NULL

as a criterion in the doc number combo's row source.

If this isn't making sense please post how you're doing the cascade.
