Changing the staff switch line to a dashed or dotted line

[Joseph Srednicki]

I would like to change the staff switch line from solid to dashed or dotted.

I based the following example on a message that I found in the Lilypond mail archive: https://www.mail-archive.com/address@hidden/msg47036.html

When I compile this example, the line is still solid.

Is my syntax incorrect or what have I misunderstood?

Thanks to anyone who can provide the answer.
