Series of numbers with variable step size; running summation

[CEI]

Hi all - I’m trying to array an object along a path curve, where the spacing is determined by a custom list of values (in the attached example they’re derived from the amplitude of a different curve). I’ve remapped the values onto the path curve length to create a list of spacing increments (the total sum is equal to the length of the path curve). But to array the objects correctly, I think I need a running total, adding each increment one by one. I’m trying to do this with Series, but perhaps it’s not the right tool, or perhaps I’m not using it correctly

Greatly appreciate any suggestions

The way you set up everything you can use the Partial Result output of the Mass Addition component.

That’s it - thanks so much for the quick solution!

This can be a bit simplified, no need to use construct domain if domain begin at 0. Also mass addition could be used just one time
