Client side Sum

[Akayy]

Info in this thread might help. I have never got sum expression worked out using the expression builder, just coded it...

"where" formatter

Wappler Version : 2.5.1 Operating System : Mac OSX Mojave v10.14.5 Archive.zip (2.5 KB) Details I’m trying to sum the salaries of 2019 & 2020 from the child repeat to display the same in the parent row. I’m getting javascript errors in my console, below is my expression. Wondering if this is a bug with the “where” formatter. child.items.where("year","==","2019").sum("salary").default(0) [image] Please correct me if I have to fix my expression. Thanks in advance.

Try with

cartForm.rcart.items[$index].lineQty.value

[max_gb]

Ok so I finally have this working after a fresh day looking at it;

{{cartForm.rCart.items.sum("qty")}}

Is simply what I needed. Thanks everyone, got there in the end
