Walls already have a "Cost" Parameter built in. If you'd like, you can interpret this as a "Cost/SF" and simply schedule it...
If you now want to calculate a total cost based on wall are, you can add a calculated value to your schedule... the trick here is to make sure your units match. So since the Cost paramter in the wall is a "Number" parameter (unitless), and area as a unit of Square Feet, you need to cancel out the Square Feet in the formula.
Note that "Total Cost equals Cost times (Area divided by 1 foot times 1 foot)" . The 1 foot times 1 foot nullifies the Square Feet of the Area parameter so that the entire equation is unitless, allowing for virtually any value to be calculated...
I've attached the project as well.

> Does anybody know of how to use formulas in Revit, for example, if I wanted to extablish a price per square foot, for a wall, or floor. How do I do it so that Revit recognizes it in the schedule. Thanks
