Subject: a agent variable changeing its value according to t

Hi all,
I have a problem of how to set a agent variable which can change its value according to t(time step)?
In my model, each agent has a variable named ¡®lifetime¡¯. It is expected that the agent¡¯s lifetime is different according to different time steps. For example: the total simulation time steps are 100, for new agents released between 1-50 time steps, their lifetime is 30(time steps), for new agents released between 50-100, their lifetime changed into 20(time steps).
I tried to set ¡®lifetime¡¯ as a global variable, and tried to change its value in the model¡¯s STEP method, but it can not be recognized by agent.
Does anyone have some idea about this?
Great Thanks!
