I am creating a basic page in w3spaces and while I've finished editing the html and css part, I'd like to add a few scripts in it. I tried to add this script (W3Schools.com), which is a countdown timer to my own page but it seems like it doesn't run. Initially I used the code provided
<p id="demo"></p>
and nothing happened. I also tried other things such as <span id="demo" class="demo></span>
and <script src="./countdown.js"></script>
but neither worked. Do you have any suggestion please as I am not very experienced.
