Can't call functions from different files

[davidguygc]

Hi, I'm sorry if this question has been answered, I couldn't find it when I searched for it, and I suck at search engines.

I have two assembly files, main.asm, and vid.asm, in vid.asm it has two global functions called blankw and display. main.asm has them listed as an extern, and when I try to call it, the program just shuts down. If I move the functions into the same file, then the program will work just fine.

What am I doing wrong?

I included main.asm and vid.asm, and main_and_vid.asm that has the two put togther

Thanks,
David
