I keep getting content.replace is not a function. Not sure what to do about that. There's only one error message...

not sure what to do here. The error log is just "doesn't work, try again".

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) {

  return content;
}


module.exports.merge = merge;

Hi Christopher Parke,

The code you have is almost correct, instead of curly braces as your replacement strings you need to use a percentage sign instead. Other than that, it works as needed when placed inside the merge function.

function merge(content, values) {
  for (var key in values) {
    content = content.replace('%' + key + '%', values[key]);
  }

  return content;
}

Happy coding!
