9/13 - It's giving me a value but still saying it's incorrect


var perimiterBox = function(length,width)
return length + length + width + width;

churns out the value of 18 but shows the error: "Oops, try again. Did you define a perimeterBox function?"



It's because you spelled "perimeter" wrong. It won't take it as correct.


Omg. I'm embarrassed. Thank you.
