The "break" statement near the end of the program is always executed. You need to add a set of braces around the statements that are to be controlled by the "if".

When posting code, please be sure to surround the code with the [code] and [/code] UBB Tags. This will help to preserve the formatting of the code, thus making it easier to read and understand.
