Calculate Square Feet and Charge by Sq FT

[MgmtSpec]

Hello,

I'm working with a client that needs to have height & width entered and charge by the sq foot. There will be other simple options such as colors. Searching the forums I could not find any threads covering this topic. Has anyone done this or any ideas on how to implement?

Think I figured this out. If I price by unit and area is equal to height x width by assigning a drop down with multiplier should work. A quick test seems to work out. The weight will change based on size so I need to investigate the changing weight by options drop down.
