I am getting an error when submitting due to the argument not being stored into the echo variable properly. Any ideas?

Here is the code I am working through in the Passing an Argument to a Function section. function returnValue(testString){ var echo = testString; return echo; } returnValue("test");

I don't think I am missing anything, but I am open to suggestions and clarification.

script.js 
function returnValue(testString){
  var echo = testString;
  return echo;
}

returnValue("test");

You want to simply return the given value to your function without assigning it to anything. The second challenge is wanting you to assign the value returned by your function to the echo variable.

function returnValue(variableToReturn) {
    return variableToReturn
}

var echo = resturnValue('whatever is passed in here will now be assigned to the echo variable')

Right on the button Joe... I wasn't really thinking that I could assign it directly to "echo" right off the get go. It also makes sense because I need to bring it out of the function to use it in the scope of the entire program. Appreciate the help!!

Hi,

The code JS code should look similar to that below:

function returnValue(testString) {
 return testString;
}

This will simply accept an argument and return it.
