Not sure if I'm looking at it right. But I wrote a program that is going to display 3 different mortgages at once. But they all stream together, I'm trying to block them where each mortgage has its own area in my GUI window. Can someone point me in the right direction?

Okay this is what I have. I'm trying to get my program to show 3 different mortgages neatly. An maybe throw in a menu prompt that you could chose which mortgage you would like to see first. Can anyone help me with that?
