Add values from two tables and sum on third

[sdsagsas]

Why is this stupidly difficult to do in this app?

Also really like the optional tag field that isn’t

[sdsagsas]

Gave up on that. screw it, one table can do it. Except it won’t sum two columns into a third with
([Col1] + [Col2]).

let me guess, this easy to use app requires about 4 more layers to get this done?

You clearly have zero familiarity with AppSheet expressions.
