Hello...of course as you can all see I am a newbie. I will cut straight to the point to prevent waisting any of your time. I am working on this inventory program for one of my classes. Unfortunately I am having a few issues that I just can't seem to figure out. I have listed below in great detail the issues that I am having. If someone could take a few minutes and help me figure out how to fix this, it would be greatly appreciated. This is my last resort...my brain hurts.
