Correct answer Ned Murphy

Do all of the traces in the function show what you expect?  If so, what makes you conclude that the ust variable is not assigned the ast value?

One thing I would recomend is that you use "event.currentTarget" instead of "event.target", just to be sure that the object to be dragged is the object with the listener assigned to it.  Otherwise, the target could be another object inside the object with the listener assigned.

Ned,thnx, what you say again worked. As shown above, I returned eventTargets to

event current Targets and I caught what I want. But this is a  very specific nuissance that I relaize I couldnt do it myself.

What is the clear difference between curretTarget and my mistake event.target ???

The simplest way of describing the difference is that currentTarget will always point to the object that has the event listener assigned to it, while target can point to a child object within the object that has the event listener assigned to it.

Here's a link to a brief article that might be helpful for you...

In the code above, there is an integer ust. this should be the index number of the event target of start drag function. But I coludnt return it in a way.

Itried function MouseDowner(event:MoUSEeVENT,num1:int):int

and

ust=....

but It didnt return. How can I return a number in a start drag function
