I want a global var for selecting sounds (0 = no sound, 1 = loop1, 2 = loop2,…). a mc indicates what sound is selected but that mc  
doesnt do anything:

Main Timeline  
Action Keyframe 1 (only one frame):

\_global.SoundLfo1 = 0;

Sub.Sub.Sub Button  
Action in the Button:

on (press) {  
if (\_global.SoundLfo1 = 0 ) {  
this.attachMovie(“wave”, “waveactive”, 5);  
}  
}

i cant see any wave  
if i delete the if thingy i can see the wave…☹  
there is lots a code missing for the sound implementation but  
if this \_global doesnt work i doesnt want to push it forward  
anymore…:\*(

i think you’re meaning to use “==” in your if statement

yes…  
its a comon mistake of lot of people… using asign (=) insted of equalation test (==)… actualy I do this mstake often to… you get a zero in your if statment and c language like pprograms stati it ash FALSE.

🙂 hare is one trick… : use::  
if ( 0 == \_lobal.SoundLfo1){}

…

if you mis and tipe

if ( 0 = \_lobal.SoundLfo1){} ypu get an error as you cant asign value to a number…
