I'm pretty sure it has something to do with my global and local settings, but for the life of me, I can't seem to figure out what I'm doing wrong. I'll post my code now.

And here are the errors. I've tried multiple things. Nothing has worked so far....

Okay, for some reason, by adding it to both of these blocks of codes,

caused the code to compile without error. However, I'm not receiving the results I want. I'm still receiving a "all files present" message when I should be receiving a "One or more files are missing..." message. Any ideas?
Deathscreton (9)
Found the problem. With all my elses in the .h file with the missing errors, I need single "=" and double '=' in the file completion function. I can't figure out how I fixed the function though, even though it is fixed, I'd still like someone to clarify.
