Okay, I'm making a hero arena style game, with 2 forces and a third for the 2 computers. We'll my question is, I can make a trigger to where the heros upgrade by moving their units onto the upgrade beacon, but problem is, when they get off the beacon, they still own the building, how can I fix this? my trigger looks like this:
Trigger("Force 1"){
Conditions:
Bring("Current Player", "Men", "upgrade protoss 1", At least, 1);
Switch("Upgrade", not set);

Actions:
Give Units to Player("All players", "Current Player", "Buildings", All, "upgrade protoss center 1");
Preserve Trigger();
Comment("Upgrade Begin");
Set Switch("Upgrade", set);
}

Trigger("Force 1"){
Conditions:
Bring("Current Player", "Men", "upgrade protoss 1", Exactly, 0);
Switch("Upgrade", set);

Actions:
Give Units to Player("Current Player", "Whatever player you want to have owning it", "Buildings", All, "upgrade protoss center 1");
Preserve Trigger();
Comment("Upgrade Begin");
Set Switch("Upgrade", not set);
}
You need a trigger to give the building back. The switches are pointless, unless you are using them in some other trigger. In fact they'll make it so if two people go onto the beacon, one of them can't use it until the other one leaves and that person leaves then gets back on. I'd highly recommend you also change it from "all players" to "whatever player you want to have owning it" when it's not in use. That way, you won't have people walking up on it and then interrupting the player's upgrades.

such as giving it to a neutral player when the current player is done upgrading? ie. give back to computer 7?

When the player gets off the beacon, you give the buildings back to whatever player who originally owned it. In this case, Player 7.

In the conditions you may want to add that the computer player owns a building there, so they can't steal the upgrade buildings from eachother.

To summarize, this is the most simple and usable way to do it:

Preplace all the upgrade buildings for neutral, P9-11 or to a spare computer player. Depends on what other uses you have for those players. Any will work. I will use Neutral in my example.
Trigger 1: Grab the buildings
Player Force
Conditions:
Current Player brings at least 1 [men] to 'upgrade protoss'
Actions:
Give all [buildings] owned by Neutral at 'upgrade protoss center' to Current Player
preserve trigger

This will automatically prevent stealing the buildings as only Buildings owned by Neutral will be given.

Trigger 2: Give the buildings back (using Neutral)
Player Force
Conditions:
Current Player brings at most 0 [men] to 'upgrade protoss'
Actions:
Give all [buildings] owned by Current Player at 'upgrade protoss center' to Neutral
preserve trigger

If you don't use Neutral (but lets say P8) you need to rewrite this trigger a little to deal with leavers while upgrading:
Trigger 2: Give the buildings back (using P8)
P8
Conditions:
Player Force brings at most 0 [men] to 'upgrade protoss'
Actions:
Give all [buildings] owned by All players at 'upgrade protoss center' to P8
preserve trigger
