Did anyone else get an error when adding .toFixed(2)?

Adding .toFixed(2) to the end of the reduce method gave an error: "filter and reduce methods have not been called yet." Why did it work for him in the video but not here when the two problems are almost the same?

The challenge is expecting the result as a number, but toFixed converts the number into a string.

This was not an issue in the video, since no numeric evaluation was being performed and the the result was just being displayed on the console.

This fixed the problem for me. Just remove the "toFixed" from your method chain and the challenge accepts your solution.
