Automatic bid refresh

Hello,

I’ve been struggling with this for a while now, but I can’t get it to work.

On the listing page I want the current bid price to refresh automaticly every 5 seconds, instead of refreshing the page manually.

Currently I’m using an ajax script to reload an external php file to place into the current price part, but I don’t know what to place in that php file.

Is there anyone who’s been able to get this to work?

Thanks in advance!
