If you aren't doing any math calculations on the column, then write a function that accepts the value as a parameter. If the value is zero, return a null. If it is any other value, return the value.<br>
<br>
If you are doing calculations, try returning a space instead of a null.<br>
<br>
The code should look something like this:<br>
<br>
Function ZeroToNull(AnyValue As Variant)<br>
<br>
If AnyValue = 0 Then<br>
ZeroToNull = Null<br>
Else<br>
ZeroToNull = AnyValue<br>
End If<br>
<br>
End Function<br>
<br>
<br>
Replace = Null with = " " if you use the column in calculations because a NULL will not calculate properly.<br>
<br>
Your calling query should like something like this:<br>
NewVal:ZeroToNull(OrgVal)<br>
<br>
<br>
Good luck
