I am setting up for my arrival into KLAX at waypoint GRAMM. It has a hard ceiling and floor restriction of 17,000 and FL210. How do I enter these into the FMC? It only ready has a proper entry at RIIVR but I did not enter it. It shows as "12000 14000"
Any help would be greatly appreciated. I have about 2 hours till I reach this point but would like to make sure I have it input a little a head of time.
Thanks for the help!
