Posting in HTML causes this sort of unparseable code to appear on the distributed version of your posting. (You didn't read the Posting Guide.)

After looking at the link:

... I'm of the opinion that you are posting in the wrong place. I think the people that run that program should be the ones you ask for assistance. After all, they say:
