Pre-made script not showing on website

I am using a script from a 3rd party company to add a plug-in to the website, i enter the script into a code block and it shows on when viewing it from the computer i added it on. But when i look on another computer the plug-in isnt there. Is worked fine when i first added it but now its been a week and its gone. any help would be great thanks.

Below is the script im using (using 4 of them but this is 1 of them)

<script type="text/javascript" src="https://4cs.gia.edu/interactive-4cs/js/embed.js?tool=color"
charset="UTF-8"></script>
