Hi Tony,
The source.dynamic() operator is an advanced tool for changing a
source dynamically in "full generality". Fortunately, you don't need
it if you have a pre-defined collection of sources that you're
changing for. In your example, you seem to want to switch to playlist
or dj1 or dj2, so there is a simpler solution in the style of what
you've seen: a switch with a fixed set of sources, and the only
dynamic part is the branch selection. However, you can't do it as in
the code you submitted (the arg variable is a string and can't be used
directly as a source, and source = arg is only defining a new local
variable source whose value is the same as arg).
Try something along these lines:
# After def of playlist and dj1 and dj2
selector = ref ""
source = switch(track_sensitive=false,[
({ !ref == "playlist" }, playlist),
({ !ref == "dj1" }, dj1),
({ !ref == "dj2" }, dj2),
])

I hope this helps. Make sure you read on references (that's what the
selector thing is) if you haven't seen it before.
