gotoAndPlay error

[darkson01]

flash cs3 on actionscript 1 & 2 (with flash 8) gives this error when i try to preview the .fla as a .swf:

Wrong number of parameters; gotoAndPlay requires between 1 and 2.

why is it doing that? what does it mean? and how can i fix it?
thanks

gotoAndPlay(parameter here)
eg
gotoAndPlay(10) - this will make the playhead go to frame 10

[darkson01]

i have gotoAndPlay(30); and it still says it

my guess would be that the timeline you have that gotoAndPlay(30); sitting on, does not actually have a 30th frame, and thus the error...

you may be missing a _root. or a _parent.

ie: _parent.gotoAndPlay(30);
