hi,

im using clearInterval() and im trying to trace it to make sure that it is being cleared. when i trace it using setInterval() i get 1 and when i trace it using clearInterval() i get undefined. so is clearInterval boolean? and if so wouldnt my tracing of clearInterval() return as 0 rather than undefined? or is undefined being returned becuase the interval has already been cleared and does not exist any more?

thanks!
