Capo?

When you're playing gutiar with a capo, do you have to change your fingerings for the chords or do you keep them the same? Just wondering because now my chords aren't sounding right...

no, you should'nt have to change the fingering, but remember wherever you put the capo, say if you put it on the third fret, your guitars bottom E is now a G. so you have basically changed the guitars tuning but your chords, say you play an open Emaj with the capo on the third fret, that will be a Gmaj, so if your playing along with a disc or something, you now need to transpose all of the chords to accomodate the new tuning...what song are you trying to play that requires a capo, or are you writing one?
