Hi, I have the following function, It is returning NaN for the number values… any help??


export function repeater2_viewportEnter(event) {

    $w("#repeater2").forEachItem(($item, itemData, index) => {

 let subtotali = Number("total")
        console.log(subtotali)
 let descuentoi = Number("descuento")
        console.log(descuentoi)
 let totali = Number("total")
        console.log(totali)

 let subtotalii = "" + fmt(subtotali)
 let descuentoii = "" + fmt(descuentoi)
 let totalii = "" + fmt(totali)

        $item("#text83").text = subtotalii;
        $item("#text84").text = descuentoii;
        $item("#text85").text = totalii;

    });

}

Hi Alex

How are you?

I don’t understand what you are trying to achieve because I cannot see where the calculation is being executed but you are missing

;

in your calculation codes and since its a .text element you need to convert the values to String like below

$item("#text83").text = String(subtotalii);

Maybe do not use viewPortEnter and use something like onReady for Dataset or onItemReady for Repeater and surely check the code where the actual calculation is happening.

You are trying to convert strings to numbers. Since your strings aren’t numeric strings, the result is NaN .

For example, you have:

let subtotali = Number("total")

The string “total” cannot be converted to a number so the result is NaN.

Another example:

let subtotali = Number("10");

This time, I am converting the string “10” to a number and the result is 10.

And yet another example:

let ten = "10";
let subtotali = Number(ten);

This time, I am converting the variable ten, which is the string “10”, to a number, and the result is 10.

I hope this helps clear up any confusion.
