Using Index(Match) to populate list

Hello,

I have workbook with two different tabs for material. On the Matl tab the user would enter the material's part number that they are wanting to use. This value in column A is then used elsewhere. I have added a second tab, Matl2, that I am wanting to automatically populate values in column A if they are entered on the Matl tab. I was able to get this to work using an index match for some of the material numbers. The ones I am having trouble with are the materials in column B with a "-##" behind them. For instance, on row 18 I have a 702032 in column A of the Matl tab. I am wanting that same 702032 to be populated on the Matl2 tab. I have attached the sheet I am working with to help. There are usually twice as many materials on the Matl tab because we have different pricing for different locations.

Thank you
