I've got a little inventory management system going, and it searches for products by name. It also loads old data from a file on the hard disk. For whatever reason, when it loads the name, it doesn't accept the name that it displays in the save/buy functions. If that doesn't make sense, just try loading a name, and using the buy function. It can't find it...
I'm probably just missing it, but could you look at this? Code is posted below.
