Hi Vipul
Thank you very much for your hint, I will try it out.
One last question: Where do I put the "$gallery_id = $params['this_is_var'];" line? I know to put the {hook h='hookDsplayShoppable' this_is_var=10} into the page.tpl.
I suspect this is javascript code, so should I add a <script>$gallery_id = $params['this_is_var'];</script> to the html field of the CMS page in question?
Thanks again!
Edit: I'm continuing to research this problem online. I think it should be relatively easy to work around it with a simple if-statement filtering out the one CMS site I want, but I don't yet fully understand the .tpl/smarty, php and html interplay how to do that. Do I imagine that too simple? Cheers
ps. sorry for the late reaction, I was out cold last week 😕
