[/FONT]Now here is the question.
[/SIZE][/FONT][FONT=Arial][SIZE=3]I have two images and I place instances of the movie clip “movieclip” on both the images. Now this movie clip has a button “bt_54”. [/SIZE][/FONT]
[FONT=Arial][SIZE=3]What I want is that when I click the first “movieclip” which is placed on the first image to go to one site – say www.hotmail.com and when I click the second ” moveiclip” which is placed on the second image to another site [URL=“http://www.yahoo.com/”]www.yahoo.com [/SIZE][/FONT]
[FONT=Arial][SIZE=3]I created a duplicate button “bt_541” in the second instance of the movie clip this changes the button in the first movie clip too! [/SIZE][/FONT]
[FONT=Arial][SIZE=3]Help would be highly appreciated.
