flash fs command in vb6

[MaxRevenge]

i made a couple of buttons in photoshop. then i animated them in flash cs3. as in when u click them they look pressed and look normal otherwise.
then i played them in vb6 form using the shockwave flash control. thats all pretty and good. but thing is when i click the button in vb6 form i want it open another form.
i searched a bit and click event of flash file (.swf) can be done in vb6 with something called fs command. as in the shockwave flash control has a fs command event the same way a command button has click event. in vb6 i write:

Private Sub s1_FSCommand(ByVal command As String, ByVal args As String)

If command = "ButtonClick" Then

MsgBox "You have successfully triggered the Click Event", vbInformation, "Flash"

End If

End Sub

in flash,i have tried and tried and searched and searched but cant find the proper code to write in the actionscript. it just doesnt work when i press the button. can anyone PLEASE guide me with this? it is frustrating beyond belief.
