C assignment bug and code fix

I am in need of a skilled C programmer to fix a bug in my code. The specific issue with the code is it doesn't work as needed by project requirments, and I need it fixed urgently within 24 hours. I have provided comments and documentation to follow, so the ideal candidate will have experience following given guidelines. The standards need to be c89, but attention to detail is a must. Thank you for your interest in the project. I will provide my current code to the one that will take the job.
