I'm trying to get a comp to use Nuke (Xtra editor). The computer has no base with resources/workers but does have 3 Command center's with nuke silos attached. i also made nuclear missile cost 0 resources and 1 second. but when i run the ai script of "nuke here" and point it at a location close to a computer ghost that i created with a trigger, it doesn't do anything. How do I get it to nuke?

Did you run an AI script to make the computers build nukes? I think you need to run the BW Terran 2 script Fill Silos with Nukes (type 2) over the area with the nuclear silos, but I haven't done it in a while though.

Also, make sure that the computer who is doing the nuking is a Terran computer.

It's not working. the ghost is just attacking my units but not nuking.

Please post the triggers or the map but it'd be much easier if you actually just posted the map.

"AI Nuke Here" work for protoss computers too. Dont know about "BW Terran 2 script Fill Silos with Nukes (type 2)".

There was a similar question recently where the ghost was ordered to move/patrol somewhere which was the problem.
Make sure you don't order the ghost.
