Update records from query results

Hi,

I am very new to programming in MS Access and I am not working in this field. So please be patient with me or delete this post if inappropriate. I have a database with two tables. I need to run sequentially through the first table and for every record run a query on a second table. The records returned contains information I want to use to update two fields in the current record in the first table. The query works fine and returns the top 2 records of the second table (sorted randomly). How to do it ?

btw: I can make the db layout and query code available, but not sure how to do it within the forum rules.

Thanks.
