i am havin a problem using a RadioButton to control labels on a panel.Anytime i click on one of the JRadio button it controls all the other panels at the same time instead of only controlling its label on its panel.

Please all hw do i go about setting my radio button to only control the label on its own panel and not all the labels on the other panels?

java
