I'm supposed to be making an inventory program with a logo. I can get the inventory part working fine in a jframe, and I can get the logo working fine in jpanel, but if I combine them it starts acting really weird. Every time I click a button, it generates a new series of buttons and labels...(Sorry about the mess, I'm trying to mesh two pieces together)
