Well that is because all you are doing in the label click events is assign a value to your variable. You will need to set the variable like you are and then do something to show the answer to the user. For instance...
CODE
Private Sub Label1_Click()
UserAnswer = "A"
' If the answer they chose is the same as the real answer, tell them so.
' Otherwise tell them they are wrong and do something else to show them that they are wrong.
if UserAnswer = RealAnswer then
MsgBox("The answer is correct! Good Job!")
else
MsgBox("Sorry, your answer was incorrect. The real answer is: " & RealAnswer)
end if
End Sub
You are just missing any code that tells the program what to do after they select their answer. In the code above we are telling it to set their answer and then compare it against the real answer and show a message if it is wrong or right.
That is all there is to it. You just need to continue along with the logic in each event.
Hope that helps!
