PL5 is correct, the important part is that the keys in parametersPL5
hash matches the id in the hash each key points to.
So for PL2 you need to use a hash that looks the same as %parameters3
but with id set to 1 since the key in parametersPL2 is 1.
And for PL3 you need to use a hash that looks like %parameters2 but with
if set to 1.
And for PL4 you need to use a hash that looks like %parameters2 but with
id set to 1 for the first parameter and a hash that looks like
%parameter3 with id set to 2 for the second parameter.
I would suggest that you use separate hashes for each playlist else its
going to be easy to accidentally set the id incorrect.
The id is used for ordering the parameters in the order you like them to
be specified by the user.
If Id write the plugin today Id probably remove the id attribute and
only use the keys in the parameters attribute on the top level. As it is
now you need to have the same info in two places.
Hope this explains it, let me know if it doesnt and Ill try to write
sample when Im beside a computer.
