getting updated data using a query

Hello,

I imported 2 excel files to ms access using connection, because my idea is to to download and use the same files but with updated data, then have the updated information by running a query. 

when I try to do this and run the query, a pop up message appears asking me to enter parameters. I don't know what to do but when I enter some random parameter I get wrong information. can you help me. Thanks.
