You've got a good start on it, but the condition to test still follows the "while". Nothing follows "do" but the beginning of the code block (the brace).

Also, since the "while" comes at the end now, the conditional expression won't have an open brace after it. But it would be "good practice" to put a semicolon to end the statement. This also helps to visually distinguish a "do...while" from a plain "while".

I think guiding you to finding the solution is much more helpful for learning that just providing finished solutions. You're close enough that you only need to make a few changes from this point, and I explained them above.

How about trying to apply those hints, and if you still have any trouble, post your modified code for some additional pointers.
