Codeless OnChange Validation?

[JJ86]

I have a form that validates immeately after a check box is checked. If the
field is empty it shows up as being in an invalid state. My question is is
there a codeless way to get the validation to happen after a single
keystroke? Users may be pressing the submit button without leaving the text
box field and all that does is validate the field (a second click will
submit). Any advice/help will be greately appreciated.

Hello

Use a secondary variable whose default value is 0. Increment that variable
when you click the button using rules. Put the data validation on the field
by checking the secondary variable value is 1.
