I made an excel form with calculations to find the correct cell. The excel form works.
On the left column is installation choices 1 story, 2 story, 3 story,
Across the top is home size 1,000, 1,200, 1,400, …
You choose how many stories, then the size of the home. Excel calculates to find the intersecting cell and return that number.
I can not figure out how to implement this into Intuilab.
