If I have an Array Variable that has a structure like this:And I've got a number variable that I want to create from the aggregate of all the from the array variable both on load and when the Array is updated with a new item... how would I do that?I've tried a few different potential paths with formulas and workflows, but I can't seem to figure this out...

someprop: "string goes here",
numberToAdd: 2

{
//...etc.

There's a few ways to go about it in toddle with the formula itself
To call them, you can use a workflow or directly set your variable with the formula
Workflow is good if you have other things you want to do but technically either will do it
Of course, those hard-coded arrays would be replaced by your variable*

Perfect! Didn't even think about the fact that there'd be a reduce function in there! Thanks
