Yeah, we don't use floating point for money.

You have = where you should have == in your if and while tests.

Here is an example.

@PP Namias

A small heads up. Where yo have lines like this in your code, you should be using a '==' instead of '=', as your assigning Yes_or_No with a 'y' in the first line, instead of checking for equality of values.

Same goes for line 237. Use double equals, NOT a single equal.

Lastly, place the break command AFTER the right parenthesis of the cases.

Hope this helps.
