What happens when you try to open the form on your superviser's computer? Are you getting any errors? What errors are they if any?
Is the "submit" button greyed out and not working? If so, can yo check if the IE has Active Scripting enabled? Here are the steps:
1. open Internet Options dialog
2. click on Security tab and click on "custom level..."
You will get the dialog below. Make sure Active Scripting is enabled.
Thanks and hope it helps.
