Tell target doesnt work

I did that action thing but cant get it work.

“Target not found: Target=”/kuvat" Base="_level0"
Target not found: Target="/kuvat" Base="_level0"

So, what is wrong in here?

on (rollOver) {
tellTarget ("/kuvat") {
gotoAndPlay(“kukka1_in”);
}
}
on (rollOut) {
tellTarget ("/kuvat") {
gotoAndPlay(“kukka1_out”);
}
}

where “kuvat” is that movieclip and “kukka_1” is fade in->1st part of the clip.
