Upgrade price from wrong selection variants and increased quantity

[antho]

Hello,
I experienced an issue VERSION 3.0.9. I use the template Flatastic, I needed a plugin that would allow me to have two distinct variants that would generate automatically a new child product based on the selection of facts and I found it, from here on simulating a purchase I noticed that when I go to make various choices of variants the price will change only the first selection, and I do so for any other information that should change the code as the product description and quantity of the product variant, the other thing I noticed is not updating price when using the + and - add a quantity greater than 1, for a second, the price is a change of transparency, as if about to change, and then returns to the original color without undergoing any change, what would it be?
I have an urgent need because he has to go online soon.

I hope I can help, thanks in advance. Undecided

Your Joomla/VM versions are insecure and should be updated.  http://forum.virtuemart.net/index.php?topic=118683.0

You must check that your problems are not being caused by your template, so test with Protostar.

Enable error display and check the js console in your browser
