Debug on validation check

[GraemeG]

Hello

I have the following code which looks at a MVF combobox for a repsonse.

If Me.cboDwellingLowerFloorStructure <> "" Then

However it give s debug Type Mismatch error.

However if I remove the multivalue it works.

Any ideas how I can get it to validate that question has been answered?

If IsNull(Me.cboDwellingLowerFloorStructure.Value) = True Then
