I keep getting that my implementation is off. Can anyone explain why this is happening?

Can anyone explain??

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 
function merge(content, values) {
  content = content.replace("%first_name%", values.first_name)
  return content;
}


module.exports.merge = merge;

That message "Your implementation is off." is perhaps not the most helpful response.   :see_no_evil:

But the code that replaces "first_name" is shown only as an example. What the challenge is asking for is a function that will replace any and all object values that are included in the template with "%" characters around the value name.
