How to do the YouTube code task

Every sunday we have a YouTube code task.
This task appear in my center-tasks on the upper right corner of the site.
You click on aply.
Than you get another page.See picture.
Where i marked the place with 1,you find a link to a YouTube video.
Copy this link in your browser and watch this video with captions on. Captions on is very importend,otherwise you will not find the code.
Somewhere in the video you will find a code with 4 numbers.
This code you fill in on the place marked as 2 on the picture.
If the code is right,you will see ,code allright.
Than you can click on reward,see the place marked as 3.
After done this all,you should get your 500 coins.

Last week someone mentioned that there were 2 codes in one video.
When you get code mismatch,watch the video further on to see if there is another code.
