[thelist] Random, Not the same Random twice

I've attempted a couple of things, one being DeleteClientVariable, and
that's not working.

In the interim, I've basically built a CFIF that says if Story1 IS
Story2, get a new random number, but that only repeats itself once.  The
success ratio is dramatically higher, but it's still not what I need.

Is there an easier way to this? Certainly it's just my lack of
experience that's causing me issue here!  I hope!
