Hey guys i am trying to make a simple cart using variables. So for every liter on the meter, the company charges 2000 which should reflect at the bottom pay button. This means that (as seen in the image) the pay button would be having 70,000 as opposed to 504,000. I have created a charge variable that is 2000 where to get the total amount to pay it should multiply the quantity times the charge but this brings the same results as total plus charge. How can i make it to add 2000 per increase in liter? Thanks
