Item Breakdown/Calculator

Hi all,

Long time lurker. This is probably a relatively easy fix, but I'm trying to create a breakdown of materials/quantity based on two variables from the "Materials" sheet.

A2 is a dropdown list of Items and Columns C-D would display the Material and Quantity needed for that specific item. I tried doing a VLOOKUP, but that seems to be the wrong function for something like this? If someone could point me in the right direction, it would be much appreciated. Thank you
