i everyone... i'm new to JavaScript. i'm stuck with my coding please any help will appreciate.
My problem with the coding is, when user enter the amount inside quantity box, the total amount will x the quantity(example , quantity 2 x MYR72 = MYR144) but the amount wont show up at sub-total. Other calculation like shipping cost & total (shipping cost + sub-total) all working fine. sorry for bad English & thank you in advanced.
