Hello Guys,

I made a quiz application that extends to a section where the user gets to see the answer he/she chose then a comment below stating whether it is right or wrong then giving the right answer. It works well. But I discovered that if I ignore a question without selecting any of its answers (using radiobuttons) it generates an error in the answers section. I have not been able to make this work , that is to make the program say something like ("you did not select an answer") when the user does not select any answer of a particular question.ie for the program to recognise no answer chosen and not give an error.

thanks in anticipation. i have attached a sample copy for you to see.use the link below
