Well it says on the check Answer spot it says checkanswer is not define and on the next button part it says next question is not defined
It seems like there may be a coding error in the program. The functions "checkAnswer" and "nextQuestion" are not defined in the code, which is causing the issue.
You will need to define these functions in your code in order to fix the error and enable the program to function properly. Once you have defined the functions, the program should be able to check answers and move on to the next question as intended.
