Messed up the Cathedral Procession

I attended an ordination service at the Cathedral today, where two candidates originating from my church were being made priests. In my capacity as a Reader, I was robed and participating in the procession - which I messed up! The two lines of the procession were supposed to pass on either side of the nave altar, to two banks of seats just above the cancel steps. A message was passed down the line, but by the time it got to me it was garbled and I wasn't sure if I was supposed to pass it on to the clergy behind me. I assumed they would just copy what the readers did. How wrong! They all went to the north of the altar, which meant that they didn't fit through the gaps and arrived at the seating area in a bunch which milled around trying to work out where to sit. Perhaps I should have passed the message on!
