I have this code block setup within my program (extracte to this test class)

I want to be able to disable the input JTextField and the JButton if no
JCheckboxes are selected,
though if one is selected i want to enable the input JTextField and start
JButton.

What am I doing stupidly wrong here..... I feel such an idiot for having to
ask this question in this NG

thankyou for pointing out my stupidity (error)
