You seem to have the right mindset here, but you just need to change some of the order of your code:

function returnValue(x) {
 return x; 
}

var echo = returnValue('Hi There!');

Is what I did to complete the code challenge. You are declaring "var echo" in the function. You should move this outside the function and have it tied to your returnValue ("echo"); statement. You can then delete the alert line as well.

function returnValue (str) {
 var echo //this is not where you've been asked to store,  so you can delete this line
return str;  
}
alert("echo"); // this is not needed, you will have to only action against the question
returnValue ('echo');  //this is where you have been asked to store with the echo variable
