In a function everything after a return is ignored, the variable or value that is after the return command will be the value that the function returns.

so to store a function return in a variable you need to create a function

function myFunc (value) {
  return value;
}

then you need to create a variable that will store the returned value from the function

var myVariable = myFunc('nick');

Yeah this still isnt working. Im not sure what im doing wrong. Where do I put the new varible at? I was thinking it would be outside the function.
