In reply to msankey:
First, you are not supplying nearly enough information to diagnose that error.
But more importantly, and it’s hard to tell from this limited information, it sounds like you might be trying to construct your up_sequencer inside your translator sequence. Which you can’t do. Look at the example again. The layered component ( which contains the translator sequence ) also builds a sequencer, and pushes that down into the translator sequence’s up_sequencer handle.
