that works for variables of type "Variant", but for others the following will work:

IIf(IsNull([YourField]), 0, [YourField])

Cheers,

Only a Variant can hold Nulls.

Sorry, I meant "others" to mean other situations, not other variable types. Data fields can hold null values, and both queries and recordset manipulation sometimes need to avoid or manipulate null values encountered.  Not sure where Adi was working in Access.
Best to convert any null data values when assigning to other than "variant" type variables--like you said, only variant can hold null, so other variable types will give error on assignment of null.
