I am making some changes to an existing form, and I wanted to make a popup message when the form loads to inform users of the new features and process. It would just be a dialog box with a message and an "OK" button that would pop each time the NewForm.aspx loads.
<script> alert("Check out the new form!"); </script>
The answer I've gotten from my IT folks is to delete the app and re-add it, which would mean I would have to individually export all my forms locally and import them once I re-added the app. Not sure I'm willing to do that.
