Hi guys, I need to calculate a rolling median for water results across a period starting on the 25th of the current month and ending on the 24th of the next month. We'll have approx. 5-10 samples per month and I'm producing a chem output table following the completion of a reporting period (i.e. after the 24th of the month). To demonstrate changes in the median over that reporting period, I'd like to have the median recalculated after each sample. Is there a way to set up my output tables to do this so I don't have to edit after table creation? 

Thanks Warwick - yes, that's right (unless we can come up with a better layout). A custom report would be worth looking into for this. I'll get in touch with you in the next 1-2 days after I get some ducks in a row.
