I tried a short jaunt from KJFK to KBOS.  I believe I put in the full route MERIT ORW ORW3.  When I got airborne just crossing into CT side, I noticed ORW3 was not there.  So I went to DEP/ARR page and it was still showing JFK.  I waited a while longer and as I got near Rhode Island, KBOS showed up.  So, I selected ORW3 and 4L.  I selected a transaction (I forgot which one now).  I hit exec, but it didn't seem to add to the route  just ORW.  NAV1 did change to what I believe the ILS freq for 4L.  What did I do wrong?

At ORW, I got the double horn and the route ended.  I tried to fly with the A/P heading, but ended up circling around three times (besides having too much altitude), before I finally learned heading.  After rereading the A/P thread here, I think I can do altitude changes now with the A/P.
