Hi Duncan.

This is something that requires more than what the software default functions can do, meaning it requires external code to be accomplished.

As the Staff won't provide support for external code, I suggest you keep your post public and wait for other members of the community to hang by and help you out with your coding issue.

Hope I've been helpful

Hello Duncan,

Have a look at the jQuery UI Progress Bar, which may suit your needs:

http://jqueryui.com/progressbar/

There are demos, source code, and documentation available at that link.

Hope this helps.

Paul
