the submit button has been renamed
The trigger for universal email at line 38:
if ((isset($_POST["SimpleContact_submit"]) || isset($_POST["SimpleContact_submit_x"]))) {
is looking for a submit button or image form element named:
SimpleContact_submit
however the submit button on your form has had it's name changed to SSPan_submit:
<input class="formButton" name="SSPan_submit" type="submit" id="SSPan_submit" value="Submit & Continue" onClick="clearAllServerErrors('SSPan_SurfaceSpecialists_ShowerPanMeasurement')" tabindex="19">
if you change the submit button name, you will need to edit the Universal Email behavior to reset the trigger.
