Re: grouping date ranges with associated sums
> example from today until 1 year - any MinFlowDate which falls within that > range will be summed assuming you have dd/mm/yyyy then: <xsl:value-of select="sum(Trade/Step [concat(substring(MinFlowDate,7),substring(MinFlowDate,4,2),substring(MinFlowDate,1,2))>= 20041129] [concat(substring(MinFlowDate,7),substring(MinFlowDate,4,2),substring(MinFlowDate,1,2))< 20051129] /StepCharge_TTBlack)"/> does the total, the same without the Trade/ at the beginning would give the sum for each trade separately (if the Trade elements were the current node in that case) David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
