Is there a formula for: If this equals that analyse array data

Dear Excel Gurus,

I am having wording issues for what I am trying to accomplish thus am not able to find solutions in the forums. Please direct me if this is a duplicate.

I have two sheets of information. Both have headers of store numbers and product columns of productA, productB, and productC with quantities listed under each product.
I am trying to return data for the matching stores but the discrepancies of products A B C in three columns.

I’ve tried playing with match and vlookup and sumif; but am doing something wrong and not receiving accurate results.

Thank you in advance,
Kate
