Add to cart button does not work

[wecreateyou]

Hello and thank you in advance.

The problem is: When I press the add to cart button, it doesn't work, it redirects me to the cart but without any product, and with the total price of 0.00€.

I only have one product to test, and you can find it here:

I am using joomla 3.3.3 and VirtueMart 3.0.9, other relevant issue is that I deleted the joomshopping before started using virtuemart.

my guess is that it have something to do with some problem with some jquery function, but I have not been able to solve it.

Thank you again, and if you need anymore information, please ask.

Looks like a configuration error. In VirtueMart Configuration/Templates/ under Activate Css Styles & Javascripts  turn on "Using the product Scripts"
Also you are loading two jQuery versions, suggest you deselect "Use external google jQuery library"  and see how that works for you.

Maybe now you should also update Joomla to 3.4.1 and VM to 3.0.9.4

Ok, just tried your recommendations, and neither of it worked

When I run the website with the console of firebug open, I get the following error:

TypeError: jQuery(...).chosen is not a function
jQuery(".vm-chzn-select").chosen({enable_select_all: true,select_all_text : vm2s...

I don't know if this is the reason of the problem.
