Hi @icos
Can you try this:
sum(rollup(Budget Exp.data.payload[0],"summ_expens"))
(Note: I don’t think this will work if you copy/paste it from here but it should work if you write the formula in WeWeb)
This is what’s happening
rollup(Budget Exp.data.payload[0],"summ_expens")
will return all the values of “summ_expens”- then if you wrap a
sum
around it, all those values should be summed
Does that do the trick for you?
