I recommend using the space infiltration design flow rate object instead of the space infiltration effective leakage area.

If you want to use the space infiltration effective leakage area object, you need to specify it in the spaces tab, not the space types tab:

Some other notes:

• The schedule for your space infiltration effective leakage area object should be an OnOff operational schedule, not an activity level.
• Add heating and cooling thermostats to your thermal zones
• You probably want to include other loads besides just interior lighting
