Advice for code integration

[eyeswideopened]

We are a first year team, there is no programming mentor. I am the only programmer and I am trying to get the robot to work with the code created. The code itself has no errors. I can get the code onto the robot but nothing works at all. I cannot figure out what is going on. Also, I only have until Friday to get the entire robot working because I am leaving for an extended period of time Friday night. It is crucial that I can get this working and I am very lost at the moment. any advice, help, tips or anything of any sort would be appreciated. Thank you -worried programmer
