In my Form I have a text box, and I have setup Control Source as follows:
=IIf([fieldA]=0,Null,[fieldA])
But I get an error with "This control has a reference to itself".
Can anyone advise how else can I achieve what I want ?

Is the control you have this formula in called [fieldA] by any chance? If so, then Access cannot tell which of the [fieldA]s you want to reference.
