Well you are running your Aloha simulation under the command environment and you did not set a necessary parameter and you did not enable the "interactive questioning" feature of the command environment, where you can enter parameters directly on the command line. So what should OMNeT do?
Either a) set all necessary parameters prior to the start of the simulation, or b) enable the interactivity feature of the command environment, or c) run your simulation under the graphical user interface and enter the required parameters in the GUI.
All ways are described in the OMNeT++ simulation manual with lots of background information too, so check it out.
