Find NULL values with range comparison type

[telepet]

I have a search form where I'm using a range comparison type to find items within certain ranges.  My data contains numbers but also blank cells.  While still using range comparison type, is there a way to search for and return results where value is blank or NULL?

Yes, it's possible, add one more criteria and select is blank comparison type. You may also make this criteria to be hidden.

Hope this helps
