How would I do this?

How would I go about calling a Script from the Map editor,  I added an attribute but it relies on Sadscript, so even though it's in the client how would I go about telling the Main text to execute it? 

Edit: just Realized Im going about this wrong :P So Where should I be telling the Attribute after it's been saved to look for its info? 
(In Lamens terms, Where do I go to edit Attributes server side?)

I think the settile command is the command in sadscript that alters tiles on the map

Err… just use the scripted tile?

or is it when a player enters a map?

You could always make a new sub for the main.txt that triggers when a player enters a certain map, use cases or something.
