hi Shaylee. Yes you have result in your square function. but remember scope. Variables inside a function are not known outside the function. So you can use a new result variable and set it to the return value from you function call.

So Simply

result = square(5)

but don't pass 5 to square. Make sure to read the instructions for the actual value to pass in.

Good luck and if you need more help be sure to post back to the Treehouse Community
