I don't think you need to send [gemhead] to the toggle--I'm pretty sure this configuration just doesn't do anything (as far as the toggle goes). If you just need to start the [metro] you can start it with a bang using a [t b f] from the number atom that sets the [metro] speed. If you need to toggle [metro] in accordance with whatever is happening in a GEM window I'd suggest sending the trigger to the toggle and to the GEM components separately. Does that make sense?
