Yes/No control

[jehm]

I want to perform a function called cancelorderonexit provided that customerid is Null ,the Yes/No control ChkStorehouse is set to True or the Yes/No field ChkWarehouse is set to True . Unfortunately the function below does not obey me, and the code is performed even though the ChkStorehouse is set to Yes
If Not IsNull(Me![customerid]) Or IsNull(Me![ChkStorehouse]) Then
CancelOrderOnExit
DoCmd.CancelEvent
End If

What is wrong ?

Try This...

IF IsNull(Me![customerid]) = True Then  
   IF Me![ChkStorehouse] = True OR Me!ChkWarehouse = True Then
      CancelOrderOnExit
      DoCmd.CancelEvent
   End if
End If

Hope this helps you...
