This is on a block which is a column algorithm as a percentage
Dear Jack Footer,
I think Down or Grand Total will help you to solve your request.
Attached little documentation (Column Algorithm). To get the downtotal you can directly use dt(Blocknumber) to get the figure and work with it inside your algorithm.
Hope it helps

Thank you! From that I was able to work out a work around using a similar idea!
