How can I transfer this code (originally for FPS template) for use in a Third Person Template?

I learned how to create a blueprint for making a character be able to pick up and drop objects: code It did not work, and I believe the reason is because it was originally made to work for the FPS template that Unreal comes with. I decided to use the Third Person template, and I think that’s why it’s not working. Am I correct? What blueprint coding should I be looking at? What’s missing, or what’s preventing this from working? Thanks!
