How to calculate 2 values ​​between them

Hello,

I would like to know what is wrong with my code.

I created a content manager whose content comes from members through a form
Except that in the data collected I would like 2 data (values) to multiply between it to give me a result.

And I would like this result to be saved to another text element in the content manager.

Here is my piece of code on which I get the following error:

Wix code SDK error: The text parameter that is passed to the text method cannot be set to the value 1800. It must be of type string.

import wixData from 'wix-data';
import wixUsers from 'wix-users';

function gain(){
 var cote = $w("#text62");
 var mise = $w("#text63");

 function multiplier(){
 return cote * mise;
         }
return multiplier();

}
$w("#text67").text = gain()

export function dataset2 () {
    $w("#text67").text = gain()
}

Cordially

Hi,
You don’t set the value.

var cote = $w ( “#text62” );
var mise = $w ( “#text63” )

Should be
var cote = $w ( “#text62” ).text;
var mise = $w ( “#text63” ).text

Kind regards,
Kristof.

I think in Javascript this should work
Otherwise use this
var cote = Number( $w ( “#text62” ).text);
var mise = Number( $w ( “#text63” ).text);

Also the function multiplier should not be in another function.

Function multiplier(value1,value2){
Var newValue = value1 * value2
Return newValue
}
Then use it as this
Multiplier(core,mise)

It’s not working sorry
