You were on the right track.

What you want to do is pass in the string 'chocolate' when you call the returnValue function. That way it will get that string and return it back to you so that you can concatenate it with the first part of the string.

Your code would look like this.

function returnValue(value) {
  return value;

var echo = 'I like ' + returnValue('chocolate');

Keep up the great work! :)

function returnValue(item) {
  return item; 

var echo = returnValue("fruit");
// To see what is being returned

This is how you pass the task youre passing in a value to the function the then edit the value in the fuction:

function returnValue(item) {
//change the value of item which is then returned to value of echo
  item = "my favourite fruit is " + item;
  return item; 

var echo = returnValue("fruit");


This would be how you edit the text how you have tried above.
