Hi JR, welcome.
The quick answer to what you're doing is to add the two tables in the query design window (aka QBE), draw a join by clicking and dragging from the VideoID field in the first table (let's call it tblUserVid) list, to the VideoID field in the second table (tblVid, I'll call it), where you release, thus creating what's called an "inner join." (You should see a black line between the two.) This will return only related records between the two tables. Then, you need to set your criteria for the time part. Let's say you add the TotalTime field (whatever you've called it) from tblVid as a field to show. In the same column, on the line marked "criteria", you should put in the following:
=[tblUserVid].[TotalUserTime]
where, obviously, you use your table/field names and not mine.

And if all this still sounds like Greek, well, post back and we'll clear it up. Best of luck.
