Dear Zenners,

I am setting up a shop where the main product to sell is rope.

I'm trying to find a way where customers can choose the diameter of the rope from a drop-down box, then type in the length in the next text box, and then choose from some other options that each add a set price.

Total Price = ( Diameter (drop-down menu) x Length (text box) ) + Extras (drop-down menus)

Is there a way to do this? I've seen it on other sites but not figured out how to do it.

The famous thread "Using Numeric Values And Dependant Attributes" is useful for creating a text box that can take numbers for the Length box, but doesn't quite show how to get exactly what I need, with regards to multiplying that by the Diameter (http://www.zen-cart.com/forum/showth...ant+Attributes).

To see the product in action, please visit http://www.ropeandsplice.co.uk/index...&products_id=1.

Thanks in anticipation

Robert
