A complete repro is: Hmm. Given that there's only one parameter, I'm surprised that doesn't work. But in the general case, what appears on the parameters input port is a sequence so that approach isn't going to work reliably anyway. The safe way to do this is to wire a p:parameters step into the top of my:params-try and read from that to initialize the variable. This will, alas, require another p:group. Longer term, maybe there should be a p:parameter() *function* that takes the name of an in-scope parameter and returns its value. Pushing the parameters into a document in order to read the value back out of the document does seem like going around the houses.
