Little textfield problem

Hi flahsguys.
I created 2 buttons as 2 movieclips and 1 dynamic textfield.
Inside one movieclip i put this code:
onClipEvent(mouseDown) {
_root.textbox_chosen.text=“test1”;
}
And inside another i put:
onClipEvent(mouseDown) {
_root.textbox_chosen.text=“test2”;
}
So they’re almost identical and when i run my movie and press on the button
i get test2 in my textfield. I can’t release why when i press my first movieclip i get
test2 text in my textfield. There are 2 seperate movieclips but when i press on the first one
it should change textfields’s.text to test1 but it changes to text2, i can’t figure out this problem =\
