Narrative:

This event occurred while departing tampa on the ended 4 departure. We were unable to get the clearance via pre departure clearance so the first officer had to call and get it. At this time I was on the phone with maintenance to clear up a fault that came up after we arrived at the gate so I was unable to listen to the clearance. We ran our gate brief at which time the first officer said that nothing had changed (in our original printed clearance); cleared ended 4 then szw. Our release clearance read tpa ended 4 cty szw vuz.... When I looked at the SID; both departure transition fixes were on our dispatch release flight plan. It specifically stated ended 4 cty then direct szw. There is no airway between cty and szw; so it made sense to me that it would not come up via pre departure clearance because the computer would not recognize it. On climb out at about FL200 center asked why we were not turning to szw off the ended 4. We told him we were cty then direct szw off of the departure. He then recleared us direct to szw. He said he showed us on the szw transition not the cty transition. Once again I did not hear the clearance directly from clearance delivery; but first officer said he did not remember hearing the different transition. This could be easily cleared up by simply not putting both transition fixes on the dispatch release. On all other RNAV sids the next point after the departure is the transition fix. Without hearing 'ended 4 szw transition' specifically; what we had in the box was what we thought our clearance was. Either way; if cty is taken out of the clearance in the dispatch release then there would have not been any confusion.
