JavaScript variable calculation not working

I’m new to javascript. I want to perform an arithmetic calculation between two javascript values as follows.
In here "issues" and "re" contains numeric values. Then I want to deduct "re" from "issues" and assign the outed value to "#bal".

Tried

$('#bal').text(jData.data.issues - jData.data.re);

Output

outs ‘0’

What may be going wrong with me ? Ca anyone help me ?

    if ‘issues’ or ‘re’ are not a number, JavaScript can’t do arithmetic calculation
    try this code:

    $('#bal').text(Number(jData.data.issues) - Number(jData.data.re));

    otherwise, the value of each is incorrect.

    check your type of issues and re,if they are String or else,
    they can not go on
