As far as I can tell the code for the links looks fine in the passage and the passages that the links lead to open up fine, so I have no idea what is the problem. Attached, I have an image of the passage itself, what the passage looks like in play (notice the strange squares with arrows next to the links), the white screen that appears when the links are clicked, and then an image of one of the passages the links should be leading to which opens fine on its own.

A secondary issue is the forward slash in the Target Passage Name.
The other issue, also noted by greyelf, is that putting a slash within the link component makes the parser think that the link is an external one, rather than an internal passage link.
