I finished a program, and I am only having one error. It is a run-time error. I have timer function that interrupts every second, and captures data. The data is then saved to a file. After collecting some points to file, the program halts on the code that attempts to open the file with a run time error. THinking that this was due to not first closing the file, I shut off the timer right before it opens the file, and then re-enable the timer after the file is closed. However, I still am getting a run time error. ANd like I said, it is after I already have a lot of data points saved to this file.

please help
