How do you?
 

Ok, how do you link: One Graal level, like a map level--> to a building level, like when you go into a building.

Hard to explain, But there is like a arrow in the top right hand corner of the graal editer. Highlight the place you wish to make a link. click the button and input the data needed.

I haven't actually used the level links for years, but from what I remember, it's pretty self explanatory.

Yeah its not that hard, you will get it... My English is on a low standard so I am afraid that I wont be able to explain to you about it :(.

Sorry.
