Calculation with comma and €

Hello,
​
I use chronoforms6 with an calculation from the FAQ.
It works very fine, but I need a calculation with comm and in the Total-Field should be displayed the €-Sign.
​
I have not knowledge about PHP or JavaScript.
​
Can anyone help me, what I must do?
​
Best regards
​
Markus

let number = yourCalculatedValueHere;
jQuery('#identifier').text(new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR' }).format(number)));
