Situation:

1. The are two buttons
2. If you click the first one a number is increaded by 1
3. If you click the second one the same number gets decreased by 1
4. For each there is an IF statement which starts a certain action

I can’t figure out how to make this work. The following script returns only one number and thus starts only on action:

function ClipSelector(i:Number):Number {  
i++;  
return i;  
}  
var nDummyVar:Number = 0;  
var nSelectorValue:Number = ClipSelector(nDummyVar);  
if (nSelectorValue == 1) {  
trace(“blah”);  
}  
else if (nSelectorValue == 1) {  
trace(“blah”);  
}  
//output: bla
