How to auto refresh bar

[biton13]

Hi, I think your plugin is just what I need but for the life of me I just can't get it to do what I want :)
Basically when I submit the page, it launches an Apex automation. The automation updates a table with the current step in the process e.g step1 - extract started, step 2 - output fetched, step 3 - file parsed etc.
I've put an sql query on the progress bar item that returns a value e.g 10 for step 1, 40 for step 2 etc. all the way to 100.
What I would like is for the progress bar to be refreshed every 5 secs (or whatever interval) and get updated with the value in the DB. Any ideas how to achieve this ? I've tried timer plugin, ajax callback but I just can't get it to work.
Thanks for your help
