[rules-users] Spreadsheet: Rule Compilation error (xxx) cannot be resolved: Keeping running total

[john@oa]

Thanks Iaune

That is really helpful.  Yes, I need the ranges to be mutually exclusive,
what is the easiest way to do that?  Feel a bit cheeky asking another
question, but you seem to know what you are talking about! I have tried adding
two conditions to enforce the range, but that doesn't seem to work - see
below.  I still get multiple rules firing.  Also can you recommend any good
resources for learning all of this, apart from the online documentation?
Would you know if any of the Drools books are any good?

 payment > $param payment <= $param  Payment Greater Than Payment Less Than
or Equal To
0  0 1500  1500 2000  2000 3000  3000 4000
