VLOOKUP error

Please help. I have been building this estimating spreadsheet and strugling with this last part til I can't stand it anymore. I"m sure it's an easy fix without the tunnelvision.

On the M & L sheet, at M7, I can't get the VLOOKUP to work. It references the materials and prices that are input in the table on the right but keeps giving me a #REF error. My other VLOOKUP works fine (it references another page that I deleted for size).

Please help.

Thanks a bunch
Aaron
