I had a similar problem the other day, I had a table (query results) which i wanted to display and a notes table which i wanted to update as i looked at the items. (i.e. I wanted to click the query results and go to the relevant notes)
to do this i created a blank form put a text box in the top then used the subform builder to put the query results in the form (creating a subform in datasheet view)
then I put my notes form in using the subform button (p.s. notes was already built but you can do it with the wizard.) then I got got the text box to display the unique id number from the query when I clicked on it - go to control source and use the builder find your form then find the new text box. it should be at the top of the list. then I linked the notes child and master to the child and master in the main form.
hope this helped.
