Boolean IsNull Syntax Issue

All,

I am struggling with getting the following syntax to work and wondering if someone can help put it right.

My CboFromState = 1 and CboToState = 2 but each time I parse this code, it skips to the End If instead of doing what I want it to do if values are found in both CboFromState and CboToState.

ElseIf IsNull((Me.CboFromState) = False) And IsNull((Me.CboToState) = False) = True Then 'DATA FOUND IN BOTH FROM AND TO STATE

Any help much appreciated.

If I wanted to see if both CboFromState and CboToState have data I would use:

     ElseIf Not IsNull(Me.CboFromState) And Not IsNull(Me.CboToState) then
     'DATA FOUND IN BOTH FROM AND TO STATE

How about:

ElseIf Not IsNull((Me.CboFromState)  And Not IsNull((Me.CboToState)  Then

Instead of an IF..ELSE..END If..  Or IF..ELSEIF..  Why not use a CASE Statement instead?  It will force a true condition which would be ideal in this example.

HTH,

Guys, I hope you don't mind. To be fair I have split 50/50 because you both came up with the same answer only seconds between each other.

Thanks guys. Exactly what was needed. It was wrecking my brain!!
