By the way, this is a basic JavaScript question, not an Ext JS one.

Are you sure your variables are numbers and not strings?

[sideeque]

Try like below.


var sum=0;
var count1=0;


sum= Number(sum) + Number(count);

[Condor]

Try like below.

That's not a good example.

This would be:

var sum = '0';
var count1 = '0';
sum = Number(sum) + parseInt(count1, 10);

Unary plus is integer conversion.

i.e.


var a = "1";
var b = "2";
var c = a + b; //"12"
var d = (+a) + (+b); //3
