Problem using keylistener to move an image

[goober69]

Hey there, got a new roadblock in my mario"ish" game that I can't seem to pass. Currently, my game reads a text file, in which a series of numbers are stored, and the numbers correspond to tile images in the program. The code displays these tiles in proper position, and everything works great. Earlier, I had a problem with drawing an ImageIcon of the main character sprite (all images in my program are ImageIcons, probably not the best method im sure but w.e it's the only way I could figure it out) overtop of the tile images, but I fixed this by adding the main character image to a layered pane. Now, here is my current problem I have implemented a key listener, and stolen someone elses idea to use boolean values to determin if an arrow key is being held down. The actual Key listener works, but when I try and use it to move the main character's image, it glitches and moves in strange ways(changing the X and Y values of the image). I've spent hours trying to figure this out and I've gotten nowhere :S PLEASE help, i'm sure it's not a complicated problem. Thanks

code:
