Sorry I didn't realise it posted the first time. It won't happen again

--- Update ---

Thanks for the tip ill check it out later as I'm out all day today so I can't do it today

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.

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

I got the program working now thanks for all your help

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.
