I'm new to Nintex Forms and it's capabilities. I know how to have my cancel button on a Nintex form call a JS function, but it's not behaving correctly. Currently, if the user clicks the cancel button a confirm() will popup and ask if they want to exit or not. If they hit cancel on their confirm exiting alert, I want it to return to the present form with their data still populated. Currently, hitting both 'ok' and 'cancel' on the confirm alert will result in exiting the form instance. How can I return them to the current window is they hit cancel on the popup? 

Thank You
