Comparing rows of data

Hello,

I am trying to compare two sheets of data, column A has the company common key code to compare.

Sheet1
ColA - Company Code: 1234
ColB - NameofCo: ACME Corp.
ColC - Price: 321.01
ColD - Code: XYZ
ColE - Country: US

Sheet2
ColA - Company Code: 1234
ColB - NameofCo: ACME Corp.
ColC - Price: 321.01
ColD - Code: XXX
ColE - Country: US



Note that the matching Company code may not be on the same row. There are many rows of Company codes.

I need to check the rows on the sheets where the company code matches, and then check if any of the additional columns (B-E) do not match. If a mismatch is found (I.e. Col.D in example) it needs to add that entire row from sheet 2 to new sheet3.

Thanks
Steve
