Experts, is the below sql how to handle Nulls?  

[import-CSM2].[Guarantee Code] and [c].[GuaranteeCode] are both number format if that matters and one has a space and other doesnt.   I suspect I am getting the error because either of those fields are Null.  I dont get a syntax just the "datatype mismatch in criteria or expression" error on run.

I am only needing to know if the below is the correct way to handle Nulls.  If so, then there's another issue, which I am not interested in knowing the solution to right now.  

here's a portion of the SQL WHERE:  (if need it all let me know)

 OR (((Exists (Select *
             from tblLetterOfCredit c
            where Nz([import-CSM2].[Guarantee Code],0) = Nz( [c].[GuaranteeCode],0)))=False))
