When you call a method, you don't spell out the type of the arguments - you only do that when declaring the method. I.e. if you want to call drawHexagon with width as its argument, you write drawHexagon(width) not drawHexagon(int width).

That said, unless the SimpleTurtle class has a static variable called width, the width variable isn't defined anywhere in your program. So you need to define it and set it to a sensible value before you can use it.

Also you're missing a semicolon on line 105 (that part of the error message was pretty clear, I think).

also make sure "width" variable has some assigned value or it may default to zero or some garbage value
