Newbie question - help switching frames without previous content

Basically what the title says, I know photoshop and illustrator like the back of my hand, but now my web design needs some flash and i really need to start from scratch, ive read the lessons etc. but im having trouble learning how to switch from frame to frame without copying all of the previous content…IE:

pretend this is a text box

frame 1: would have #1
frame 2: would have #2
and so on…
but when ever i get to the last frame lets say 12345
when i go back to the previous frames they all have 12345 :puzzle: very confused, im probably staring the problem right in the face but im overlooking something. thanks for any help in advance
