Problem In Sound Controlling Code: It Causes Strange Behavior

programming flash
1

[FONT=Arial]I created two simple prototype programs ( see below ) to test an algorithm of sound control in a loaded SWF before adding it in more complex programs.[/FONT]
[FONT=Arial]Both use separated .as files. My intention is to load subsequent random external SWFs to replace what exists before in the more complex program.[/FONT]

[FONT=Arial]The problem is that the Toggling operation behaves in a weird way. It switches OFF in the first time, ON in the second time but fails to switch OFF again in the third time.[/FONT]

[FONT=Arial]What seems to be the problem ?[/FONT]
