Ok so I’m using Lewis Filford’s tutorial as a base for a Spider-Man game I’m making, and one of the blueprints for the web zipping function has an error. I’m using the tutorial, but Instead of just using the download link to the project, I’m trying to my my own version of it so I can kind of learn. I also want to change things up and make the game different/ Anyway here are a few images of the errors
Yep, that’s exactly how you learn 
You’re on the right track!
From the screenshots you’ve provided, it seems like you just copied & pasted a blueprint code from one blueprint to another. And the blueprint where you copied the code into doesn’t have the variables that are being used in the code. To solve this, you’d need to create those variables in that blueprint as well.
Hope this helps!

Thanks! I went and promoted all of the variables that I didn’t have previously, and made sure everything was properly connected. When I did, however, there are still some issues.
Also in the video, there is a node that says Multi Sphere Trace by Channel has it’s Trace Channel set to the name of the Event Graph (ZipPointTrace), and I can’t do this for some reason. Also I cannot send any more images unfortunately 
It’s because it’s a custom trace channel. By default you only have the visibility and camera channels. Here’s a tutorial that you can follow to create your own:
Thanks! I created the Trace Channel and was able to fix some of the easier output errors, but I had a little bit more issues to sort out.
I don’t quite understand THESE output errors, so could I get some help?
Seems like the same thing for that function or whatever it is as well. (Can’t see anything) How do you even call it? Anyways, you’d be better off making everything from scratch, following the tutorial you mentioned step by step instead of copying & pasting since that would make you learn what those codes do on the way You said you wanned to adjust the tutorial game to your liking, right? You’d need to grasp the whole concept to be able to do that in the first place. Because in the future, you might encounter more issues when you slightly adjust something and might have no idea what’s causing those.

I understand that, but he is not AT ALL detailed in the video. He says what he does, but instead of it being a detailed tutorial telling us what we need to do, he doesn’t. So, I kind of have to guess what parts hes talking about and go into the project download link he left to try to do things the right way.
How can I correct things just by guessing what you’re doing, while you also guess what another guy’s doing? 
Is that the first tutorial series you’ve checked out to learn Unreal? If so, there are many well known YouTube channels that you can watch beginner tutorials from. There are also some beginner tutorials you can find on this website as well
Okay I found the tutorial you were talking about. It’s not a making from scratch kind of tutorial, the guy just explains how the code which he provided works. You’d need to know some basics before trying to make it yourself without any guidance.
Here’s a nice starting point:
Keep in mind that even after you gain experience, you’ll still struggle to edit other peoples’s codes since you won’t have an extensive grasp of the context unlike the person who created it.
Hope I was able to provide some guidance on your confusion
