The following code is a function difined in my \_root. If I create a variable \_root.alpha and reference that in the function everything works fine. But when I use the function with an internally difined variable it doesn’t work. I need to be able to call this function from a number of movies in different timelines. Any help would be appriciated.

[INDENT]fade = function (alpha) {  
if (alpha\<=0) {  
alpha = 0;  
myColorTransform = {ra:‘100’, rb:alpha, ga:‘100’, gb:alpha, ba:‘100’, bb:alpha, aa:‘100’, ab:‘100’};  
my\_color.setTransform(myColorTransform);  
break;  
} else {  
myColorTransform = {ra:‘100’, rb:alpha, ga:‘100’, gb:alpha, ba:‘100’, bb:alpha, aa:‘100’, ab:‘100’};  
my\_color.setTransform(myColorTransform);  
alpha -= 25;  
}  
};
