GoLang : I'm simply trying to import functions

I’m hoping someone is familiar with GoLang. I’m trying to import a function from another file but I get a console error saying the function is undefined. Cant figure out what I’m doing wrong.

I pushed it to my github repo for easy viewing : alkapwn3d/vending-machine-go

Go is stupid. If you want to export something, the first letter has to be capitalized.
