I converted some .png images into buttons in Flash CS5, and then I added code to the first to link it to a web page (which is still currently on my computer). That worked fine, but when I try to add a link to another button, it either puts the new code in BOTH buttons, or it just replaces the code in one button and deletes it from another (depending on which of two methods I've tried). How do I get past this? If it helps, all four buttons are in the same time line layer.
