[rules-users] Duplicate variable issue

[Eric Miles]

After doing some more tinkering, it doesn't seem I can reference
anything in the accumulate conditional unless it comes from the pattern
or init section of that accumulate conditional.  I can not reference
globals or pattern bound variables from the rule (outside of accumulate)
or I get a duplicate parameter exception.  What am I doing wrong?  If I
haven't set this up incorrectly, I have to think this is a defect.

Thanks,
Eric
