Looks good to me. How many nested 'if's to you expect to have? If you go over 3 or 4 I would seriously look at Schedule Keys. They are much easier to manage...

Thanks, 

I guess I will have to use the Schedule Keys approach because (as you know) there a number of Use catagories in the Code. I am struggling with the Schedule Keys approach because it is so counter-intuitive to take a schedule used to track door keys and apply it to a Occupant Load / Code problem. Also, when i create a Schedule Keys schedule, based on Rooms) the Room number parameter does not appear in the available fields column?

Do you know of a thread or example a first timer like myself could follow to work this out using the Schedule Keys approach?

Schedule Keys arent for tracking actual keys they are to equate one value to another in a schedule. We use the table name as the Key name. Schedule keys do not schedule the actual items of that category. Rather they create possible relationships (ie exiting) that can then be used in a schedule of that category.

Hopefully the attached drawing will help explian things a little better.
