Directions on Advanced Calculation

I need advanced calculations based on other fields. This is for a printing company where the user will enter the width and height of their product and then multiply that by the square foot price AND then multiply that number by the material chosen in a different field. I could find no tutorial and no post clearly explaining how to do this.

My problem is exactly the same as this person's problems http://www.gravityhelp.com/forums/topic/variable-pricing-multiplier-option-instead-of-fixed-price but I can't even get to where he started.

Thanks

Ok great, I'll try this tonight. Is there an explicit guide somewhere that explains this thoroughly that I can look at?

Thanks

I've got it close, but my total price isn't reflecting the correct banner product price, which is the $15 number:

The backend of my form looks like this:

I'll be integrating it with my Woocommerce cart next like this:

Yea here's just the form: http://wordpress.coastalrepro.com/gravity-calculation-test/

Here's the product test page: http://wordpress.coastalrepro.com/product/hanging-banners/

Can you export the primary form and send it to me at peralty@rocketgenius.com please?
