Narrative:

When in cruise flight over the top of sav VOR. We were filed the HUSTN2 arrival into clt. Once over the top of sav VOR the aircraft turned to what I thought was navee; instead it turned direct to hustn. Within 30 seconds the ATC controller asked if we were filed on the HUSTN2 arrival into clt. I was the pilot monitoring so I said yes. The controller then said I show the aircraft left of course for the arrival. I then realized that the aircraft was indeed going to hustn instead of navee. I quickly went into the FMS and redid the arrival; confirmed and executed the FMS direct to navee. The controller never said anything else; and we continued back to the original course and arrival.the crew did review the flight plan in the FMS before the flight; as the captain I confirmed and copied the flight plan. After the event I asked the first officer; who put the flight plan in the FMS on the ground; if he understood what had happened. He realized that when he put the flight plan in the FMS he didn't add the transition to the arrival. So instead of selecting the HUSTN2 sav transition he put sav; HUSTN2 with no transition into the FMS. When I reviewed the FMS I read; sav; HUSTN2 but didn't realize the transition wasn't inputted. Due to this the fixes on the arrival where not added in the FMS between sav and hustn. I fixed the FMS and corrected the aircrafts course. I do not think the aircraft was more than 1/4 mile off course. Make sure to watch the first officer when he inputs the route into the FMS. Review the route closer on the before start checklist.
