Ho do I clear a checkbox

Hello Friends,
I have a form with many checkboxes. Each item has a field name of SelectData".
It works just fine. I would like that checkbox to be deselected and blank when I use that select form again. For instance after I select “Multi Child” and print the document and I go back to the select form I do not want “Multi Child” to be selected again. I put this in the beginning of the procedure but it did nothing. «Multi Child» = “”![

If Multi Child is a variable, follow that statement with a ShowVariables statement.

«Multi Child»=""
ShowVariables «Multi Child»

Worked perfect. Thanks so much for the quick response.
