exporting from 3dsmax (note key missing)

[bboy-tiger-]

Its been a while when i was last time working with 3dsmax, so i forgot how to export model correctly, when i'm exporting a model, it shows me a message that following animation sequences are missing their note key, so what I must do ? I knew that before but now I dont know anymore . Help ?

Dope sheet...note track...rings any bells?

Y i know all of that, but i can u explain the "note track" more ?
I'm using dope sheet, its an animation list or whatever, but i dont get it, what is "note" track, my mother language isnt english, so i need explination for that, kinda stupid, but i get understand so pls explain a bit more like to little baby
I got there start and end keys, like, walk_______walk attack_____attack, and so on.

Edit: seems all ok now, but now i have "float keys" problem xD, i had same problem 2 years ago xD.
