Code challenge at the end stage 3 not working

For some reason I can't get the code to work. The answer (in my mind) should be a simple replace, and when I test the code on my own, it works the way it should, but treehouse won't accept the answer. I know this is simple. What am I doing wrong?

Hi Andrew, can you post your solution? Maybe it's a Treehouse temporary problem with the challenges or a little detail in the code that the challenge is not accepting.

This is how I did:

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

module.exports.merge = merge;

Hi Rafael,

Originally I did: content = content.replace('%first_name%', values.first_name); and treehouse wouldn't take it. Then I found something similar to what you did and copied and pasted it into the challenge just to see if it would work, and it did. What you have is the correct answer.

I was about to write that I didn't understand why it worked, but I just got it.

Thanks:)
