APA style... Citation: 3, 4 or 5 authors

Dear colleagues

I need to cite two times a paper with four authors. With APA style should apear all of the authors the first tim, but only the first one “et al.” next times.

However, EndNote makes all the citations apearwith all the authors. I.ve tryed to edit the style, but it isn’t possible to make this chnge (at least I can’t!.

Can anybody help me?

Thank you,

Pedro Novais
