Add to Cart button

Hi jxsn,

You could do this with either a JavaScript in the page or with PHP in the OnSubmit Before box.

But I suspect that you might be better off looking at the Simple Caddy extension for Joomla and using that to build up the Cart contents.

Thanks Bob! Yeah I downloaded Simple caddy already. it Doesn't handle multiples options. I have a few questions for the developer. Thanks for the suggestion.
