webgem #1:
A) LIMITED field (comment/message):
Besides adding the code below in it's own webgem,
must add to the FORM statement in the START THE FORM webgem:
form name="sampleform" (you can name it anything you want)
must add to the FORM FIELDS statement in the FORM FIELDS webgem:
before the message field to inform, add a row (bolded) and include this statement:
(Note: 700 character limited input!)
after the message field, add a row (bolded) and include this code:
<script> displaylimit("document.sampleform.Message",700) </script>
(the name in this code must match the form name in the START THE FORM webgem!)
<script>
