Want initial button 1 to disappear, so other button 2 can be seen clearly

i have read the tut by kirupa on creating a full flash site. but its not exactly what I want to do. i want the button labeled 1 to disappear completly so button 2 can be seen. This pertains to something I am trying to do in my more complicated flash site, but i tried to simplify it here. maybe a hint on how to design/layout my site so button 1 performs desired action? i will explain more if this is a dumb way of accomplishing this. dont want to post junk, unfinished work on my site but i will if need be to solve this problem… and I know no one wants to hear any q’s about preloaders…but thats later, much later.

I have attached two fla files in one zip which reference each other, keep in same folder. I cant believe im telling the person who is gonna help me these most remedial of needs. dar

im new and dont want to ask too much.
I’m gonna thank you in advance for helping me:)
