Can't really solve this chalange, not sure what the issue is

index.js 
var utilities = require("./utilities");

var mailValues = {};

mailValues.first_name = "Janet";

var emailTemplate = "Hi %first_name%! Thanks for completing this code challenge :)";

var mergedContent = utilities.merge(emailTemplate, mailValues);

//mergedContent === "Hi Janet! Thanks for completing this code challenge :)";
utilities.js

You're close. But if you attach ".key" to values, it's going to try to get an item that has the key name of "key". You need to use key as an index.

Also, replace doesn't change the source, so you have to assign the result back to the source for the change to stick.

So you want something like this:

  content = content.replace('%' + key + '%', values[key]);
