Unable to figure out how to go back into switch statement

millerizi (25)
So I select a trivia option, I go through answer the questions get the total right out of total questions asked, then it takes me back to menu, but when I click on menu it won't go to switch statement, do I need to reset variables somehow, I know I need to reset the score variable, but that's a small problem compared to the loop not working. Any ideas?

I cleaned up this a little bit, I put the If Score under each CASE into a string function so I don't have repetitive code, but still can't figure out why I can't complete a game and once at back menu try another one.

ok, so you are saying calling the int option will basically initalize each time we call that function, so it resets, and then use the DO to gather is input and as long as its not 6, I will have to try this, see if I am understanding it correctly, thank you
millerizi (25)
This was very helpful, I did have to create some functions to reset my counters, for some reason they were calling it to not loop after going through a case, so I could loop thru once, but if I tried the same one again, it would just stay in the do, section because the counters were not reset. Thanks again.
