MC to MC transition with button

[font=Times New Roman][size=3]This has got me stumped. I’m building a site with six pages. Each page is contained in a movie clip with a transition in and a transition out with stop(); in the middle. What I’m trying to do is trigger the “transition out” from page A to “transition in” page B.[/size][/font]

[font=Times New Roman][size=3]Example;[/size][/font]
[font=Times New Roman][size=3]Button A is clicked and “transition in” is played in mc_A. mc_A is then stoped in the middle.[/size][/font]

[font=Times New Roman][size=3]Button B is clicked and plays “transition out” in mc_A then contunus to “transition in” in mc_B.[/size][/font]

[font=Times New Roman][size=3]I hope this makes sense. [font=Times New Roman]I can’t find an answer anywhere.[/font][/size][/font]
[font=Times New Roman][size=3]Thanks[/size][/font]
