Parsing error, setting up view more button

Why would I get a parsing error on the line in green. My button is #button11. I copied the code from Corvid and changed the (#myTextElement") to (#button11). Am I missing something?

let fullText; $// variable to hold the full text
let shortText; // variable to hold the short version of the text

// For full API documentation, including code examples, visit http://wix.to/94BuAAs

$w.onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 40;
// read the full text and store it in the fullText variable
fullText = $w(#button11).text;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText = fullText.substr(0, shortTextLength) + “…”;
// set the contents of the text element to be the short text
$w(#button11).text = shortText;
//TODO: write your page related code here…

I think the wix button element uses a ‘label’ property and not a ‘text’ property.
