count & sum of items that fits specific parameters

Hello,

I have a 2-part Calculation question:

PartA:

In App-A, I want a total count of how many "items" from App-B fits a specific parameter, that references App-A. below is the code I used, but getting back "0"

var cat = @All of Estimate Won?;
var stat = @All of Work Status;
var count = 0;
for(var i = 0; i < cat.length; i++){
     if(cat[i].indexOf("won") > -1 && stat[i].indexOf("closed") > -1){
         count += 1;
   }
}
count

PartB:

I want the sum of a field, "Sum of QBO Total" from App-B that fits a specific parameter, that references App-A. below is the code I used.

if ((@All of Estimate Won? == "won") && (@All of Work Status == "Finished"))
{@Sum of QBO Total;} else { 0;}

____

App A: Global Contacts

App B: Whiteboard

• App B References App A via reference field. 

I made a previous post asking about the same problem, but I don't think I had enough details. I really appreciate your help on either post!
