Passing Date Field and Rid to my codepage

So despite Dan Diebolt's recent inactivity, I can just feel him counting my sins from wherever he may be, but I'm going to try my best and give the solution I would do in a pinch.

Basically, I would divide the HTML into variables around the dates/IDs you want to use, e.g.

Name: [URL 1-1]
Value: <p id="demo"></p>
<script>
var countDownDate = new Date("

and so on, then in the Formula using [URL 1-1] & ToText([Date]) & [URL 1-2] etc., etc. Hope it works for what you're doing, and good luck!
