    Hi IronMan,

    Please post your code in
    // Your code goes here.
    Plus, mention the exact error message from console rather than simply mentioning the error lines. That would help us get to the point quickly.

    Thanks for your co-operation.

    Wink Re: cannot find symbol variable lines 24, 25, 44, 45, 63, 64? Help!

    Seems from the overview of the code that the variable "randomNumber" was never declared, but still its getting used in the switch clause. You are trying to use it on every line 24, 25, 44, 45, 63, 64 and thats where the errors are coming from.

    First declare the variable [int randomNumber] and then use it, otherwise the compiler will complain with the message "cannot find symbol".

    I hope you have the clear idea now.
