I can't get any of the data bindings formatting to work. My problem currently is Group By, but I've tried others and whenever I apply any formatting I see no data.
Without the formatting, I can see data in the repeaters.
I've created a very basic page to test with. I'll e-mail a link to the page I'm having the problem with.

We've received your link - please move the following line:
<script type="text/javascript" src="ScriptLibrary/dmxDataFilters.js"></script>

after:
<script type="text/javascript" src="ScriptLibrary/dmxDataBindings.js"></script>

That worked, thanks!
