USING OF BUTTONS

Hi,

What i was trying to do is show characteristics of a word using oval shapes around a rectangular box which contained the defined word. I wanted to present it in a different way by using NEXT buttons for every characteristic using triggers and different slide layers for every characteristic.

I was fairly successful till the first one. But at the second NEXT button even though it shows the second characteristic, I don't want the first shape(charachteristic) to appear again. Can i have a remedy for this? I am attaching a file for further clarity.
