okay here is wha tim doingi have the irs all set up good as far as i can telli enter kclt as departure airport and katl as arrival airport on the fms route page #1i automatically go to dep/arr and select HOR1 SID with HARAY Trans. then i go to dep/arr again and select MACEY2 STAR with SPA Trans. These meet back to back so no routing needs to be put in in between.i then look at the page 2/3 on the route page and it says route discontinuity... why? it does the same thing if i enter the dep/arrival runways also.

Take the waypoint after the discontinuity and insert it into the line that the discontinuity is in, this and more is discussed in the manual believe it or not. :-PRyan
