http://forum.virtuemart.net/index.php?topic=90961.0 i figured out of myself for VM 2.0.0. After upgrading to VM 2.0.2 and fixing product template override, is there big problem with add to cart button in category view!

I have exactly the same problem as users last post in highlite topic. 

Strange thing is, that after click to add to cart button is modal window two times generated - first with name of product and shop backlink, second with text "was added to cart" and show cart link.
Cart is empty.

Any ideas?

EDIT:
Add to cart button in detail product view works fine without problem. 
It looks like JS problem and i alco try to combine setting with Google JQuery library loading and WM Jquery loading. Doesnt help.

I was also wondering, if it is a problem with old problem, since from 2.0.3 has change layout structure and there is more template, even all old functions should be deprecated, but available. I load standard template from 2.0.3 and edit it accorading the highlight topic and doesnt work too.

EDIT:
after delete this parts of code from category template, it looks like, add to cart button started works. but i need more conclusive testing.

Hello,
I have done these changes (edit2, ie, delete the parts of the code).
From the category page the 'add to cart' button works for me, but if in this page I use the search button, in the result, the 'add to cart button' does NOT work...

I hope this can help

Hello,
If you change in he file: \components\com_virtuemart\assets\js\vmprices.js
the line addtocart = cart.find('input.addtocart-button'),
to addtocart = cart.find('input.addtocart-button').unbind("click"),
only one box is opened and the 'add to cart' button works!
And all the changes related to the top of this post (jQuery(document).ready(function ()...) are not necessary.
Thanks
