You can use the VLOOKUP function in Excel to achieve your desired result. The VLOOKUP function returns a value from a specified range (your PRICING sheet) based on a matching criteria.
Here's how you can set it up:
On the CONTRACT sheet, add a column for the square footage input.
In the cell under the square footage input, enter the following formula:
=VLOOKUP(A2, PRICING!A:D, 2, TRUE)
where A2 is the cell containing the square footage input, PRICING!A:D is the range of the PRICING sheet where the data is stored, 2 is the column number that contains the pricing details, and TRUE is to return an approximate match if an exact match is not found.
Drag the formula down to fill the rest of the cells under the square footage input column.
This will return the pricing details based on the square footage input on the CONTRACT sheet, and display it directly under the corresponding square footage.
