Hi all,

When I ru my flash application, the following error gets displayed in the output-box at runtime:

ArgumentError: Error #1063: Argument count mismatch on DynaAccess\_fla::MainTimeline/onScrollCancel(). Expected 1, got 0.  
at MethodInfo-374()

Can anyone reply me, What for is this error?

Thanks in advance…
