Unkown error when I try running this script (HELP)... please

[Exodious]

This is alot if code so I won't be suprised if nobody can be bothered to help, but appreciate if you can
The problem is, I create one instance employees/manager salesman or employee, and no problem
When I try an instance of employee, manager and salesman, it crashs, I thought it may be a memory error but changing the model size to medium/large makes no difference.
I'm still experimenting but its beyond my meager efforts
Anyway, code (if you can be bothered, you might want to copy code to c prog)

go straight down to bottom (void main(void))

char* monthName(int monthInfo);
int monthName(char monthInfo[8]);

//well, the days of the week, hours worked for each week
