I want it so that a certain product to be multipied by 5% of the total price. So, if they buy 50 of a product that is $1 then I want the total price to be $50 * 5% = $52.50

Can I do that with the base install of MS2-MAX? I know that attirbutes let you add (+) and subtract (-) but, I tried mutiplying (*) and it doesn't seem to work, it does some other weird math

Thanks!
