Code error message when creating an expandable text box

HELLO i have 10 working expandable texts on my website using these codes:

let fullText10; // variable to hold the full text
let shortText10; // variable to hold the short version of the text

// For full API documentation, including code examples, visit Velo API Reference - Wix.com

$w.onReady( function () {
// how many characters to include in the shortened version
const shortText10Length = 0;
// read the full text and store it in the fullText variable
fullText10 = $w(“#text122”).html;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText10 = fullText10.substr(0, shortText10Length) + “”;
// set the contents of the text element to be the short text
$w(“#text122”).html = shortText10;
});
export function button14_click() {
// check the contents of the text element
if ($w(“#text122”).html.length < fullText10.length) {
// if currently displaying short text, display the full text
$w(“#text122”).html = fullText10;
$w(“#button14”).label = “Show less”;
} else {
// if currently displaying full text, display the short text
$w(“#text122”).html = shortText10;
$w(“#button14”).label = “Show more”;
}
}
