JSPDF Libary fails

Hello there,

I am in need of some assistance with a Webflow project that was previously owned by a colleague who is no longer with us. I have been tasked with adding a button that downloads the webpage as a PDF, essentially creating a downloadable exposé. So far, I have managed to obtain the button with its ID and have written custom code for it. However, I am encountering an error that says “uncaught referenceerror: jspdf is not defined” when attempting to load the jspdf library.

I am relatively new to Webflow and unsure of how to proceed with resolving this issue. Any suggestions or advice on how to properly load the jspdf library would be greatly appreciated. Thank you in advance for your help.

The Custom Code without an added Libary is Working. Only in Use with this or other libarys doesent work…
