I have currency fields in my form.  I have defaulted them all to be blank, but I'm guessing because they are currency fields, they still populate with 0 on the forms?? 

I have a workflow that will update another field if there is a value entered into the currency field.  My Run-If action does not have Is Empty or Is Not Empty, therefore when I set my Run-If to be greater than or equal to 0, it passes through and updates the other field every time.  Additionally, 0 is a valid entry a user can put into the field.

How do I setup my workflow to properly check if the end user entered a value?

Thank you,
