Good Work!
I also discovered that Labview 8.2 has a "radio button" control, which allows you to have MUTUALLY EXCLUSIVE selections, if that's what you need. I'm certainly glad they have the radio button now, because I once had to figure out how to do that 'longhand", and I've since forgotten how I did it. (Hint...it was NOT a trivial problem!)
Anyway, with the radio button, you can pipe the output to a case structure, and put each of your selections in a new case. Actually, I really like this problem, because there are so many divergent approaches to solving it. Really gets the old brain follicles going!
