I making a website where I'm going to sell rope and I need some help.
The rope comes in different diameters and each diameter has a different price. Let's say 10mm is 4 dollars a meter. I want the customer to be able to select the length he wants and then add a flat amount is he wants something at the end of the rope, like a splice or an eye. I would look like this; 15 meters of rope x 4 = 60. And then if the customer want an eye at hte end of the rope it will cost an extra $5. How do I do this? Do I need to make a script?
I also need the price displayed to change as the customer makes changes to the options.
I hope someone is able to help :/
