How do I make new hospitals light up in the mapview?

With the Lot editor I can make my own hospitals. The SC4 hospityals, and most of the hospitals on the Net, show up in green when I open the mapview, but the ones I made myself do not. Of course I can see the circle, but I can't see the building itself.
Is it a very complex process to correct this, or not? Can someone give me a clue?
I Lotted some hospitals myself and am working on a large medical complex: the Academic Medical Center, which covers a complete large city.
I have chosen a different approach: the Medical Center covers the whole city, but each building can hold up only to a specified number of patients. When you need more room for your growing number of patients, you add another building.
But to make it complete I think the buildings should show up green in the mapview.

It might be a missing Occupant Group.

Can you check which OG's your hospital building has?
If you don't know how to do that, you can attach your hospital's SC4Lot file to a post here and I'll take a look.

Thanks, I will check the occupant groups.
Maybe the smartest and simplest way is checking wich occupant groups are active/assigned to existing hospitals and then assign exactly the same to my own hospital. With LEprop this should not be too hard, I guess.
Didn't have time to do it, but probably will this weekend.
Andreas helped me to use occupant groups for assigning lots to the desired menus, so I am aware of your list. Thanks for that also.

Edit on october 6th.
I tried to, by checking with LEprop the occupant groups in Deadwoods Indoor Sportscentre.
It showed:
Building: Civic
Building: Health
Building: Striakble Health
Building: Hospital
Building: Ambulancemaker
0xB5C00DDB = 0xB5C00DDB
0xB5C00200 = 0xB5C00200

In my own lotted hospital I saw all the five that start with "Building". Even several times...? What could it mean? Maybe because I added several props to the lot? I deleted all untill I had just one item of each. The two rows of numbers scare me a bit. Should I add these by hand?
