    some reason it jumps from q1 to q5, and discarding going from q1 to q2 and from q2 to q3

    Try debugging the code by adding some println statements to print out the values of the variables that are a problem every time their values are changed so you can see what the program is doing and when and where it is doing it.

    if (question.equals(q1))
    That compiles but makes no sense.
    A JLabel is not a String and a String is not a JLabel. It does not make sense to test if they are equal.
    If you don't understand my answer, don't ignore it, ask a question.

    Did you look at the API doc for the class to see if there are any methods that will do what you want?

            	if (point <= 15)
    			 {
    			 	question.setText("Try Again!");
    			 }
    			 else if (point >= 15)
    			 {
    			 	question.setText("Congrats!");
    			 }
           	}
        }
    }

    did i put
    	if (point <= 15)
    			 {
    			 	question.setText("Try Again!");
    			 }
    			 else if (point >= 15)
    			 {
    			 	question.setText("Congrats!");
    			 }

    at the wrong place? because when I click on sumbit after the first question, it goes straight to the Try Again/Congrats, it passes all of my codes before that..
    how do i fix it?

    Try debugging the code by adding some println statements that print out the values of the variables that control the logic and to show the execution flow so you can see what the computer sees and understand why the program does what it does. Keep adding printlns as needed so you can see what the code is doing.

    can you use println's for JLabels? I thought println's are only for system.in.println

    By println I meant: System.out.println(<put stuff here that is to be printed>);
    These will print on the console.

    For debugging, you should use System.out.println() to print the contents of the programs variables and to show program flow so you can understand what the program is doing and be able to change it to do what you want. You do not want debug output going to labels.

    In the action listener method there is a chain of if/else if statements.
    You should add an else at the end of that chain and in that else you should print out some information about why the else is being executed because none of the preceding if statements were true.
