Can you show me how you use the action in ATS by posting a screenshot?
One common cause for ATS not being able to recognize a widget is that the widget name is not unique on the page. If you are familiar with the browser's console, you can open that and use a jQuery statement to find all elements on the page with the (full) selector that you use (where you replace “textBox1” with the name of your widget.
If you show me a screenshot of the action and the result of the jQuery in the console, I can try to help you out.
With kind regards,
