yup. you're using $0 inside a message box. $0 in a message box has no
special meaning, since dollar variables have a different meaning in
messageboxes: $n gets replaced by the nth element of the incoming
message. there is no use in using smaller n than 1.

you would need something like this in order to compose a message
containing the $0 value of the patch:

[$0]  <- not a messagebox !!!
[$1-bla(  <- this is a messagebox

this would give you something like '1023-bla'
