Run an update query....
docmd.runsql(update "code you would get from sql when running the query normallly...")
just run this code on the event required....
It isn't more complex then that.
If you have the rest ready. zip the file and post it. I will find a way to update it doing what I have said and you can see the code.
Maybe I am just not explaining myself well, or you don't understand what I mean, either way, let me fix it and make it so, it will be faster.
Gimme the zip db, and explain what you would like to happen on what event. To further help me, you could add comments in the place where the event should take place ok.
Thanks
