I have an array of cells in one sheet, which I am trying to find the minimum value, based on a condition.

Example:
Sheet: Data Sheet
Floor SquareFeet
1 500
1 550
1 425
2 345
2 370
3 500
4 400

Sheet: Summary Sheet
Floor 1 Min. Sq.Ft
1 425
2 345
etc

I need to be able to sort the data sheet on various other criteria, so the value that the summary sheet retrieves needs to be dynamic. If anyone could help me on this, it would be greatly appreciated!!
