I helped you in the support center.

ok... could you put the solution in here. I bet you would get less tickets.

There is hard to pinpoint the problem, because it's different for every site. That's why I can't post a ready made solution. Here's a quick troubleshoot for more advanced usres:
General causes:
-Javascript conflicts with other components/template (topic)
-Not setting the VM-attribute/formnames correctly.
-Make custom attributes optional-hack not correct (topic)
Causes in the form:
-Database has the wrong fields, or formkey is not in DB
-forms has validation or other script errors
-when sending mail the setting of after/before mail in DB setting differs.
-Other formsettings can be checked in settings-mode of module.

Best ways of testing:
-Test the form seperatly from the link in the CF-backend. make sure it sends without errors and gives the JSON from the ajax_returnform as feedback. Make sure the values are stored in the correct table (there is no formkey there, that's correct).

-Always check the module in settings mode in the flypage.
-Check the page in IE JS-debugger for script-errors.
When the module is not responding (spinning forever) check the feedback of the ajax request in the hidden iframe in the form. There is probably an error there.
Hope this helps you any further..

I have this same error. When I try to add product to cart nothing happens. The form itself seems to work fine but when I try to add it to cart, Firebug gives me this error: "formCartAdd is null, new Ajax(formCartAdd.action, opt).request(); "

Other products without the form work fine except when you add them to cart, it doesn't show the product name right. There's only "<".

I'm using RocketTheme Mynxx theme, Joomla 1.5.20, Virtuemart 1.1.5 and VM-Chrono Module. Same problem occurred also with default Joomla theme.

I have tried every trick I can find without success. My deadline is closing and I would really appreciate any help.

Thanks in advance.

I'm also having trouble with add to cart. Using RT Akiraka theme.
Been able to eliminate many issues following advise listed here.

But, how do I "When the module is not responding (spinning forever) check the feedback of the ajax request in the hidden iframe in the form. There is probably an error there."?

Still looking for some resolution....
