Now i am totally of when i have reviewed the video quite wel but still have not found the error which is causing error

I have cycled over the keys exactly as in the video because implementation it is impossible to tel what proceded it.

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) {
  //Cycle over the keys
  for(var key in values) {
     //Replace all {{key}} with the value from the values object
     content = content.replace("{{" + key + "}}", values[key]);
  }
  //return merged content
  return content;
}


module.exports.merge = merge;

For your code to work, you can either change the 'emailTemplate' variable to this line 

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

or you can update the place holders in your merge function to be '%' - '%' instead of '{{' - '}}'.
