Copy frames?

I dont know if this belongs in flash 8 forum but ill try to ask here.
I am trying to copy fames in a MC and paste it after the the copied frames. The frames has text inside it and i want to change the text each time. But when i do that the text changes in all places the same time… Can i copy frames and change the text so that the text is different in each?

Sorry for my crapy english…
