Help with using a Function from a separate file.

I'm currently trying to get this particular code to work. In it, I have a forward reference in main.cpp that doesn't seem to do its job. I created the actual function in another source file, but when I try to compile my program, these errors occur.

You have to add the file to your project.

You have mystuff.cpp in your project, but the other image shows that you are trying to use functions from safestuff.cpp.

Hey, it works now. Excellent. Thanks!
