Caching pages messes up my Tab-script in Joomla

[koenox]

Hi all,

 

I'm using Joomla 1.6 and during the construction of my website I turned of page caching. Upon finishing the site I turned caching back on and this act only messes up 1 of my pages.

 

It's a tab script (SP Tab) in which I list the 6 products I sell on a different tab. The content of every tab is a seperate module. When I turn caching on (either progressive or conservative) then all 6 tabs show the same product (module). 

 

Since the php code of the script is kind of short and in this file it refers to caching, by posting the code here maybe you guys can tell me WHY on EARTH if I turn caching on, the tabs all show the same product.

 

MANY thanks in advance.
