DIY ABX tests from abxtests.com - I can't get them to work

[GuidoK]

So I want to do some ABX tests between audiofiles, and want to use https://abxtests.com/
However, I can't seem to get them to work.
So this would be my link:

ABX

Listening tests in the browser

abxtests.com

It's an open dir with everything in it, the two flac files and the yml file:

Index of /zooi/draaitafels/ABcomparison/Hooverphonic/edit2

But somehow the link won't work, and I assume I've done something wrong in the syntax of the .yml but I just can't find what I've done wrong (I'm not a programmer)
I've deleted a lot of the form stuff in the syntax file on the github page, basically using the minimal test configuration.

Can anyone help me?
Do I have to register my yml file/link at abxtests or something like that?

I've never done an ABX test but HydrogenAudio sort-of "specializes" in it and there is an ABX-plug-in for foobar2000 (free). You can download foobar2000 and the plug-in and if you have any questions you can ask on the HydrogenAudio forum.

Yes I know about the foobar plugin and for personal ABX use I use lacinato, but I want to use abxtests.com for the ease of use to just post links so that other people can do the tests I plan to do.
I know lacinato has that option when running/hosting own scripts (just like abxtests.com) but that is out of my league (I can't even get that yml script running for some reason....)

This is the script I'm trying to run (if that was not clear, the yml file is in the open dir):

name: Hooverphonic comparison one two three LP CD

    #### Hooverphonic comparison one two three LP and CD

    This is an ABX comparison of the LP and the CD. There are 10 iterations. You
    will see your results at the end.
  
    You can start once the files have downloaded.  They are ~70MB in total so this may
    take a while depending on your connection speed.
  
    If using Safari and the "START!" button isn't available after enough time to download the files
    has elapsed, try using Chrome as this is sometimes an issue with Safari.

    ### Hooverphonic comparison one two three LP CD

options:
  - name: LP
    audioUrl: https://audio.home.xs4all.nl/zooi/draaitafels/ABcomparison/Hooverphonic/edit2/Hooverphoniclp1.flac
  - name: CD
    audioUrl: https://audio.home.xs4all.nl/zooi/draaitafels/ABcomparison/Hooverphonic/edit2/Hooverphoniccd2.flac

tests:
  - name: Hooverphonic comparison one two three LP CD
    testType: ABX
    options:
      - LP
      - CD
    repeat: 10

It's such a simple script that I feel really stupid that I can't get it to work....
