You can't use conditional operator like that I mean this && this = false. The structure is this > 10 && this > 10. I mean both sides left and right of the logical operator must have condition tocheck if it's true or not after that the conditional operator check's the results if both are true than the whole expretion is true and so on. One more thing you check if something is equal to something with '==' and '===' operators, with the '=' you only asign values remember that. Hope you got it :)
