How do I multiply the Final Sale?

[bluefox_W]

Good Day Everyone!!
  So, I'm making a website to sale bags of candys, for parties.... so the client must add the candies to the shopping cart and have the price of that candy bag... then somehow ask how many bags do they want to purchase... and then multiply the total for the quatity of bags to have the Grand Total.

   for example, some cliente add:
- 1 kitykat bar $5
- 2 ferrero rochet $10
- 2  canels gums  $2
- 1 coloring book $15
- 5 popsicles $10
.. TOTAL $42

how many bags do you want???    or quantity??
= 10

GRAND TOTAL 420

is there a way with virtuemart?, tried with child product but not multiplying.. Maybe with shooper field asking, but I dont' know how multiply the value.. is there a paid plugin for this???  Any help it's very appreciated
THANKS

Hey man,

This plugin is very well for this solutions.
See on this:

https://victus.easy.minion.cz/jidelnicky/muj-victus-individualni-balicek

you select 42 products (select first product with 42 pcs) and add to cart.
On the cart you can change quantity for this product builder.

OF course You have to develop a little bit for your needs.
If you don't developer, then we can.

of course, I said:

Or you can develop from start - maybe 50-100 hours?
As you wish, is your option
