Double Mouse overs

I have one mouse over effect…

on top of that button, i place another button…

so layer 1 has full movie image, when you place your mouse over it, it goes to image 2, on mouse out back to image 1

now on layer 2 i have a text link button,

when i place mouse over the background on layer 1, it does its thing…but as soon as it hits the text link button on layer 2, the background image on layer 1 acts like i dont have the mouse on it…

how do i double the mousever…so that when i place mouse over text link, the background image still reads as if i have my mouse over it…

assign them layers?
