I Need Help With Doors Plz

[Synthetics]

Hey guys, i was wondering if anyone knew how i can get door to work when a unit enters a region and when all units leave the region the doors close i've tried 3 different ways and can't get it to work here are the ways i've tried.

1.
Events
Unit - A unit enters OD top <gen>
Conditions

Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
[1] If - Conditions
Then - Actions
Destructible - Open Gate (Horizontal) 1225 <gen>
Destructible - Open Iron Gate (Horizontal) 0479 <gen>
Else - Actions
Do nothing


[2]
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(OD top <gen> contains (Triggering unit)) Equal to True
Then - Actions
Destructible - Close Gate (Horizontal) 1225 <gen>
Destructible - Close Iron Gate (Horizontal) 0479 <gen>
Else - Actions
Do nothing


[3]
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Number of units in (Units in OD top <gen> owned by Player 1 (Red))) Greater than or equal to 1
Then - Actions
Destructible - Close Gate (Horizontal) 1225 <gen>
Destructible - Close Iron Gate (Horizontal) 0479 <gen>
Else - Actions
Do nothing

None of these work, however if i have the same trigger but with wait for condition it works but causes massive delay after a while of hosting the map i was wondering if anyone knew how i can fix this.

Thanks for your Time and all help is much appreciated

Unit Enters region

Open Gates

Unit leaves region

If (amount of units in region == 0)
 close gates

Have you tried something like this:

test
    Events
        Unit - A unit enters *Your Region*
        Unit - A unit leaves *Your Region*
    Conditions
    Actions
        Wait 0.10 seconds
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                *Your Region* contains (Triggering unit)) Equal to True
            Then - Actions
                *Open the gates*
            Else - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        ((Units in *Your Region* is empty) Equal to True
                    Then - Actions
                        *Close the gates*
                    Else - Actions

You can try to disable the wait in the start of the trigger, if it works remove it, if it doesn't enable the wait again.
