Adding footstep sounds

I get a little bit confused how this is explained in the Wiki.
I added a region, named it, and added the AlsScript code.
According to the lesson I have to delete the text settings so I did.
Exported the age, but there was no sound, only the region was visible.
Then I removed the AlcScript and add the text properties again ("the old way").
Now I hear the sound and the region is invisible.
Why is the old way working and the new way not or did I forgot something?
Regards,
Frits
