Dave,
4.0.3 shouldn't be the issue, as it had mostly some cosmetic fixes for the admin area. 4.1 is going to be released in the next few days, so I'd recommend just waiting for that version if you're planning to upgrade.
Unfortunately though, I'm honestly not sure what's going on. Everything on the page looks right. I found a post on LinkedIn's developer forums about other users with this issue (
here
) and they've narrowed it down to a Javascript conflict of some sort. I don't see anything terribly out of the ordinary on your page though. Even on a bare-minimum page of your site, it still doesn't work:
www.beingtotallyme.com/my-weight.html?tmpl=component
Can you try the following (even if just temporarily to test):
1) Disable the Mootools Upgrade system plugin
2) Turn off SEF URLs
Not sure if either of those will make a difference, but hopefully helps narrow some things down.
Thanks,
Alex
