    >Help! Help! Help!
    The first thing I can tell you is that you have a bunch of syntax errors such as not closing or opening braces and using = when you meant ==. I didn't bother going any further in debugging because completely left justified code that is any longer than a page is a pain. Post your code with the code tags and I'll check it more closely since quite a few of your bugs will be more easily found with properly indented code.

    You might also want to state exactly what your problem is. Very few of us have enough time to go through reams of unformatted code looking for potential improvements, but most of us will point out errors if we know what you want help with!

    Thanks, now all I have to come up with is the functions for Split, Double, and Insurance. I really appreciate everybody's input. Sorry I got so nasty. I was up most of the night working on this. I have to turn it in on Wednesday for my final!! I hope I get it all done before then. I had a final exam tonight and another one tomorrow night. I also have to work full time. Well enough complaining! Thanks again. If any of you have some ideas for these other functions let me know. Especially for the Split function.
