C++ dosn't work and gives weird errors.

I have decleared multiple variables in the .h fail, but it keeps on saying they are undefined in the CPP fail, eventhough I have included the .h fail in the CPP.


Also I get this weird error.

These errors dont let me start my project. All of these errors came up when I removed a bCanEverTick from an unrelated fail, because it was causing a random error.
