Twitter button problem,the quote generator project

i hava a trouble with the twitter button it shows a blank page,can anybody help me,here is the code pen link https://codepen.io/mehdij/pen/goMZQN/
ps: it is not responsive i did not use bootstrap,and i will style a little the page

document.getElementById('quoteDisplay').innerHTML= quotes[randomNumber]
       };

function tweetQuote() {
       var twitterURL = 'https://twitter.com/intent/tweet?hashtags=quotes&related=freecodecamp&text=';
       var q = $("#quotedisplay").text();

Only thing i caught was lack of consistent casing with quoteDisplay (q uses quotedisplay)

thanks a lot ,i changed the values to’ quoteDisplay’ to both of them,but i still have the same problem

thank a lot,i changed the javascript in order to put the quote into the tweet,it does not work,it shows a an empty quote,since i am beginner i have no idea how to change the code to fill the twitter box,would you
mind helping me to do it

oh thanks you!!!,finaly it works!!!
