I realize that this is a common question but for some reason I've been having some weird trouble with it. I am trying to have a drop down list that populates the following cells underneath it with part numbers found in sheet 2. (The attached excel sheet shows what I'm talking about). Everything seems to work fine, EXCEPT when I click on 'Green' from the drop down list. Instead of populating it with the column headed 'Green' in Sheet2, it instead populates it with the 'Cafe' column in sheet2. The rest of the drop down categories work fine though! I am using hlookup, fairly simple- I don't see why it isn't working for that one column. Any help would be greatly appreciated as this is driving me crazy!
