I want to build an expression where I can see the accumulated sum of one field. I started with an RangeSum function and everthing looks fine but on the second view I saw that when I click on a date the accumulation will start from the beginning. Is there a possibility to create a function which gives back the "total" accumulation when I click on a specific date.
Please look at my example...
PS. My goal is to build a function in the frontend and not in the script enviroment.
