Set Graphic Alpha ?

[El_Thierro]

Hiya! I'm having some troubles with some script... This is what I would like to do:
I have this graphic symbol in Flash, let's call it 'graphic1'.
Above the graphic, there is a button, 'button1'.
No I need some code, so when you move your mouse OVER 'button1', the alpha of 'graphic1' is set lower (so it becomes less visible). Still following me ;) ? How should I do this?

[kode]

change the symbol behaviour to MovieClip... and use the _alpha property. =)

button1.onRollOver = function() {
graphic1._alpha = whatever;
};
;)
