Random numbers across multiple objects

Ok here is the thought process :

Start
Object pops up and stays up for 5 seconds
Then pops down
It stays down for a period of seconds decided by

llFrand

Then pops back up and the process repeats

This works fine when I have 1 object but when I copy that object say 5 times, all 5 objects pop back up at the same "random" time. How do I get a different random number in each object? Here is the code I currently have for my random number generation:

 state_entry()
{
rand_res = (integer) llFrand (5.0)+1;
llSetTimerEvent(rand_res); 
}
timer ()
    {
    state pop_up;
    }

Can u paste in the whole script because i see u use more than one state.

the problem is when you copy the object the script is still running with the same time as defined in state entry, the variable is set

i bet if you reset all the scripts so they all called different random numbers it would work (or just call a new random number in the timer event)
