I have nothing set to null. A method runs that is suppose to change my Jtextfield text on a click event and I get this error:

n/m figured it out

I had made my text fields instance variables

but when I created them in the method, I reMade them:

JTextField mylabel = new JTextField("blah")

where as it should have been:

myLabel = new JextField("blah")

So my other method could access the text.

with swing, it's usually best to just follow the patterns that sun uses.
