Ok, I have spent days on this and have gotten nowhere. Can somebody help?

I have a CFGrid displaying information from a database. I would like a user
to be able to select a record and somehow pass the url to an edit screen so
they can access the full record. I see entries in the help file for using
Href and targets but I'm afraid this isn't clear. I already have the "edit"
screen which successfully accepts a url variable passed to it, I just need
that url variable set to what the user selects in the grid.

Can somebody help me out?
