Hi guys, I require only a bit of help here, basically when I dial in my route etc my sids never match up with my final destination, or runway of the arrival airport. 

Can somebody give me a step by step of the fmc routine for the following flight:

Depart: EGAA, Runway 25
Arrival: EGCC, Runway 5L

Basically I enter the LISBO waypoint as the first waypoint and then try MIRSI as the second en-route to EGCC, but doesnt seem to work, I need a step by step tutorial really of this specific set up as I watch other ones and they work fine, its just when I attempt to dial my own routes in I get into bother.  P.S i know how to set the plane up etc for perf init etc and CG% etc etc, just the way points.
