MIDI jukebox

Jeg har fået en MIDI jukebox, som ikke virker. Der kommer en fejlmedd. hver gang man trykker på Play. Selve koden ser sådan ud:

<!-- TWO STEPS TO INSTALL MIDI MENU:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document  -->
