Hi,
I'm trying to implement a crossfade between sources in my switch. My
script works fine without the crossfade elements added to the scrip. But
if I add transitions=[crossfade, crossfade] to my switch, I get a parse
error. I can't see where the script is breaking. I added it below. I'm
hoping someone else can see the problem.
