Quite a few things to fix here. Remember that Java is CASE SENSITIVE! Many of your errors is because you had a lowercase "s" when you should have had an uppercase "S". You also had an extra "d" when there is no d in the method name.

You also forgot data types on your variables and you don't add the variables to the GUI, you add the checkbox controls to the GUI.

Read through the extra comments I put in. They will explain to you were your errors are and how they were fixed. And in the future, explain the problem rather than just throwing your code out there.

We are brilliant people, but we are not here to be your compilers.

Thanks! Enjoy!
