I'm stuck on this project and not sure what's going wrong. I need to return the temp conversion of a users input on click. Any help would be appreciated.

I hope you look at this code and give you a better idea about how to work with HTML elements. Not have much time to explain right now, sorry...

Definitely, just got out of basic HTML and now starting to work with javascript. It is still a bit confusing at the moment.
Thank you so much
