Gravity Forms doesn't support pricing based on measurements, it only supports pricing based on price and quantity. The only way to implement something like this would be as a customization using custom jQuery to perform the custom calculations. You would need to know jQuery in order to implement something like this, or hire a developer that is familiar with how to do custom jQuery. </p> https://legacy.forums.gravityhelp.com/topic/form-calculation#post-29199 Wed, 06 Jul 2011 06:53:52 +0000 swissjohn 29199@https://legacy.forums.gravityhelp.com/ <p>I have a form question.</p> <p>I have a series of options for roof sizes, for example:</p> <p>Size Price</p> <p>2000mm x 2000mm £1,000<br /> 2000mm x 2500mm £1,500<br /> 2000mm x 3000mm £2,000</p> <p>Then I need to sell glass for the roof but this is sold by the square Metre m2 and I have 5 different options for glass at different prices.</p> <p>So my 2000mm x 2000mm roof size would be 4m2</p> <p>How could I make it so that when someone chooses an option for roof size (example option one 2000mm x 2000mm) it automatically calculates the amout of glass needed (in m2).</p> <p>then when they choose an option for glass it multiples the m2 by the price per m2 and adds that total to the final total.</p> <p>I hope that makes sense!</p> <p>Kind regards</p> <p>John </p>
