Hi Rob,
Basically it's a Joomla tab module called Dinamod. The tabs are in module postions I added into the template's xml file and then in the VirtueMart product you call those modules by:
I have chosen for Dinamod because all other tab tools give problems either with the videos shown in the tab or they are not 100% IE compatible. One major timeconsuming thing in this site was making the site Operating System compatible. To my knowledge it can be viewed on any system, Mac or Windows or Linux without any javascript error or warning.
