Actionscript geniuses, please help....

[Intensepix]

I have this script which I need to use but I would like (if possible) for 

someone to tell me(ASAP-tonight if possible) exactly what each syntax means, 

especially the "numChildren",the periods,etc..

here it is below,


On (Press)

      Set Variable: "numChildren" = ..:numChildren

      Set Variable: "counter" = 1

      Loop While (counter <= numChildren)

            Set Variable: "arrayElement" = "..:child_" & counter

            Set Variable: "control" = Eval (arrayElement)

            Begin Tell Target (control)

                  Go to and Stop (1)

            End Tell Target

            Set Variable: "counter" = counter + 1

      End Loop

      Set Variable: "..:selected" = _target

      Go to and Stop (2)

End On


Thank you for your time, I really appreciate it,
