It looks like there are two problems here. The first issue is that your second update is using the posted WADAUpdateRecordID value from the first form. This will not work since this values is not present if the second form is used. The name of the element that holds the id in the second form is WADAUpdateRecordID2. You will need to edit your second update to make use of this form element.
The second problem is that the hidden form field that your second form is using for the id is not being set, here is the field from the second form:
html:
<input name="WADAUpdateRecordID2" type="hidden" id="WADAUpdateRecordID2" value="" />
You will need to set the value of this element in the second form to the id from the recordset for the record that is being updated like this:
php:
<input name="WADAUpdateRecordID2" type="hidden" id="WADAUpdateRecordID2" value="<?php echo(rawurlencode($row_rsStickyHH['id'])); ?>" />
