Linking Radio Button Results From One Web Form to Another 'Result' Web Form

Question

Essentially, what I am trying to do is allow a user to take a quiz, that consists of five questions. When the user is done with the quiz they will click the button at the bottom at that form. I am trying to get the result from a selected Radio Button in a Radio Button List, which I believe I have set up, to a Result Web Form that will say if they got each question right or wrong. The problem I am running into now is that there are two Web Forms that a user can take a quiz on, and I can't seem to change the 'Result' Web Form's text boxes to public. Then I could manipulate the text box in the corresponding button method. So, I added a button in the 'Result' a button that when clicked will take a specific quiz. I have yet to find a way to set up an IF STATEMENT, so I don't have to specify a quiz. I'll put my code below.
