The last line of the challenge instructions address your problem.

You shouldn't have any code that isn't inside of a function.

I hope this helps!

thanks so much,

i cant believe i didn't have to repeat code just go to the line before line 22 and 'def Main():' wow. i really needed to calm down and believe programing is not as difficult as i think.
