Thank you thank you thank you!!!!! You have no idea how much this means to me. I've been struggling with this thing for days and it is mainly because I don't know enough about programming or Matlab, and while I'm trying to learn along the way the basics of it, I have a job, 4 kids and 19 credits, which 2 of the classes are masters level. I really appreciate your patience with me. I promise that next time I post something I'll triple proof it before I send it. Again, thank you very much for your help.
