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

If you dump out the xml

Mantis is right in what the output is – if you don’t merge the condition column you’ll get a drl as below (If there exists a Condition (c1) such that its payment > $param(1) AND there exists a Condition (c2) such that its payment <= $param(2).**** If you merge the condition column the constraints apply to the same Condition object with the comma being the implicit and (if there exists a Condition c1 such that its payment > $param(1) AND its payment <= $param(2).

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?

Empty cell means: the column's snippet is not included in the rule. Since you don't have a constraint for Application() you can employ a trick: remove the column and prefix the text application: Application() to the text in cell C7. In Rule 1, do you really want to test whether a payment is not greater than zero? Do you realize that Rules 2 and 3 would both fire for certain payment amounts? You can update a String field.

However, I can't even update the field in the table. I have attached the spreadsheet for review. In this spreadsheet I am simply trying to set the score, and that is failing with: DScoringTable] Rule Compilation error application cannot be resolved My goal is to have different decision tables that will all need to update the same score, and keep a running total of the total score. Any help very much appreciated! I hope that I am just missing something obvious. http://drools.46999.n3.nabble.com/file/n3322713/demo-score-sheet.xls demo-score-sheet.xls In future I may wish to also update a String field and keep concatenating to that field, is this possible?
