    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    saying i need to have a while statement at the end

    Wow, there are errors all through this code you are going to have to deal with. I'll start with helping you out with your do/while problem. You have a couple "do" statements that are missing "while" statements. I would recommend checking each do/while statement to make sure each one has a while at the end of it (HINT: you're missing 2). After you get that fixed we can get onto your other errors. Mostly typos.
    Writing code is your job, helping you fix and understand it is mine.

    Please read the forum rules. Double posts are not allowed, and doing so doesn't win any favors (actually, the opposite) with unpaid volunteers trying to help. I have removed your other post

    So what do I do? Do I get rid of the "do" statements or do I put "while" statements on the end and if so I'm not sure what to put in the while statements

    There are quite a few syntax errors and other problems. I'm surprised you wrote such a lot of code without discovering the simple ones?!? (did you copy it from somewhere? )

    Maybe you could refer to some guides that talk about incremental code development:
    "Develop in little steps, compiling and running after making each small step. These steps can be very small - even after adding just one statement you might want to compile and test the program again. " (ref)

    You should also revise the comparison == and the assignment =

    The while and do-while Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)
    Your biggest error is the missing while in the do while loop. There are particular instances when a do while loop is preferable. Make sure you really need to use them. Your code is quite difficult to read. I'm not sure of your level of experience, but I suggest breaking the program up into smaller, more manageable chunks (methods).

    Fix the small errors first, like the undeclared variables.
