thanks msalama... i'll try your flag logic. For some reason i am having trouble following the logic of sgtmikes setup... might be having a dense morning...
it seems like once his Flag 1 is set the first time, it will never have a value of 1 again... then the continuous action is basically counting 15 second intervals and triggering a random value for 1 between 2 and 30... once it gets its value, I would not have thought it woudl reset the 15 second counter... maybe i'm wrong?
if a loop is what I'm after - maybe a 2 flag trigger might be simpler? I'll report back soon.
