Default Change blanks to 0 (zero)

What can I enter in the criteria that will recognize all of the blank fields?
There are more than one thing that can appear as a blank. There are nulls
and zero lenght strings.
Use this to pull both --
Is Null OR ""
That is two double quotes.

I need to do an update to change all blank fields to a 0 (zero). In the
criteria, I have tried IsNull and it is not returning any of the blank
records. I have tried IsEmpty and I get a message that say mismatch. What
can I enter in the criteria that will recognize all of the blank fields?
