I've listed all of the errors in the program and identified where they are. I've been working on this all morning, but i can't figure our how to fix the remaining errors. Can you please help me to find a solution to finish the program, also, can you add edit or improve anything within the program itself.

, but i'm not sure how to solve the fix the action listener problem. Also, i am unable to display the total score within the program as shown bellow /*** error with tscore. In addition, the guess, which is the user input is oddly the incorrect return type. If it is possible, can you physically edit the text yourself to adjust any of the errors.
