Update / Delete / Insert quandry

I am working on "update" areas for my end users. This is where they can go in and update and / or edit information in their profile. The problem I'm having a hard time getting my hands around are those areas where they can have multiple entries. One of the tables allows for a user to enter up to 5 choices. The table would look like this: RecordID TypeID 101 3 101 5 101 9 .........etc. So I can do a straight update - where if they wanted to update the example above and change the 3 to a 12 that works fine. What if they wanted to leave TypeID: 3 but delete 5 and 9. Or another scenario, if they wanted to leave the existing ones but add a fourth record. Is there a way I can handle all this in one fell swoop? I thought of "deleting" all current records first and letting user make all new choices. Not sure if this would work well if many users though. Any suggestions ? Thank you, Stuart
