Debugging my first app and variable scope is throwing me off

Can someone explain why my functions aren't accessing the variables I set outside them?

Ugh, global scope gets everyone at first.

Global scope is the worst. Caused me so many issues. Took ages to figure it out.

My first big JavaScript project had like five variables with the same name. Total mess. Took me a whole weekend to fix all the weird bugs it caused. I still get nervous using var instead of let or const. It's one of those lessons you only learn the hard way.

Remember getting so lost in scope issues I almost gave up coding. I had a variable that kept changing when I didn't want it to, and it was all because I didn't understand closures. It really is a universal rite of passage.
