Hello everyone,

As the title of my post might be a little hard to catch, let me explain a bit more…

I’ve got several combobox.  
When changing their value, each of them launch the same action, except that they do it on different clips.

Let’ say  
list1\_cb will work on clipA\_mc  
list2\_cb on clipB\_mc  
list3\_cb on clipC\_mc  
…

instead of doing  
list1\_cb.addEventListener(“change”, function1);  
list2\_cb.addEventListener(“change”, function2);  
list3\_cb.addEventListener(“change”, function3);  
…  
and than create a function function1, function2, function3 which would be the same, except acting on different clips

I would rather do  
list1\_cb.addEventListener(“change”, common\_function(clipA\_mc));  
list2\_cb.addEventListener(“change”, common\_function(clipB\_mc));  
liste3\_cb.addEventListener(“change”, common\_function(clipC\_mc));

and then, only define a function common\_function which would work on a movieclip known as a parameter.

Unofrtunately, it looks like it’s not possible to put any parameter to a function called by the “change” event on a combobox.

Would anybody have an idea about how I can do that ?

Thanks a lot to all of you who read this and tried to help me
