I haven't reached this far in the course, or looked at the challenge in depth, but could it be because you have a special character in your code (ã)? Try replacing it with a regular 'a' and see what happens :-)

The challenge first asks you to define a function named returnValue , assign it any single argument, and then returning that argument:

function returnValue(vacilão){
 return(vacilão);
};

Next it wants you to create a new variable, echo, and have that value be assigned the result of the returnValue function with any string. That would make it:

function returnValue(vacilão){
 return(vacilão);
};
var echo = returnValue("test");

So echo is going to be created, and then defined by the result of "test" passing through returnValue

The challenge first asks you to create a function which takes one argument and returns the argument immediately:

// Name a function: "returnValue" which takes one parameter
function returnValue(argument) { 
     return argument;  // Returns the argument when the function is called
}

You are then asked to create a variable: "echo" which is the result of calling that function and passing any string you'd like as the argument:

var echo = returnValue("My argument"); // Creates variable "echo" and assigns it the value of returnValue(argument)

So the total result looks like:

function returnValue(argument) { // Names a function: "returnValue" which takes one parameter
     return argument;  // Returns the argument when the function is called
}

var echo = returnValue("My argument");

Also, I am not sure, but I think that 'ã' counts as a special character. I would try running the script without it and just using the letter 'a' or any other un-augmented character.
