Deselect building trigger

[zll7]

I have this trigger which is ment to not allow you to select more that 1 builing at a time of the same builing type.

Build
    Events
        Player - Player 1 (Red) Selects a unit
    Conditions
        ((Triggering unit) is A structure) Equal to True
    Actions
        Set tmpInteger = 0
        Unit Group - Pick every unit in (Units currently selected by (Triggering player)) and do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (Unit-type of (Triggering unit)) Equal to (Unit-type of (Picked unit))
                    Then - Actions
                        Set tmpInteger = (tmpInteger + 1)
                        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                            If - Conditions
                                tmpInteger Greater than 1
                            Then - Actions
                                Selection - Remove (Picked unit) from selection for (Triggering player)
                            Else - Actions
                    Else - Actions

The problem is that this trigger does not allow you to select even one building... My personal though on what the problem is, is that the trigger upon selection adds one and thus deselct( even with only 1 building)... So i need to modify this trigger to add up the number of buildings selected... WHICH i dont know how to do. Anyone have any ideas for this?

Might an easier way to do the whole thing be:

Events:
     A unit is selected.
Conditions:
     (Triggering unit) is a building equal to True.
Actions:
     Set SelectUnit = Random unit from (Units selected)
     Pick every unit in (Units selected) and do Remove (picked unit) from selection.
     Add SelectUnit to selection.

I don't have WE in front of me but that's basically it.

How about this trigger?

Build Copy 8
    Events
        Player - Player 1 (Red) Selects a unit
    Conditions
        ((Triggering unit) is A structure) Equal to True
    Actions
        Set Selectunit = (First unit of group (Units currently selected by (Triggering player)))
        Selection - Add Selectunit to selection for (Triggering player)

> Set Selectunit = (First unit of group (Units currently selected by (Triggering player)))
> Selection - Add Selectunit to selection for (Triggering player)

Adding an already selected unit to a player's selection won't do much...

Yeah that trigger doesent work any other ideas?

I got one that works great...here it is...

limit building Grey
    Events
        Player - Player 9 (Gray) Selects a unit
    Conditions
        ((Triggering unit) is A structure) Equal to True
    Actions
        Set slelected_units = (Units currently selected by Player 9 (Gray))
        Set tmpinteger = (Number of units in slelected_units)
        Selection - Clear selection for Player 9 (Gray)
        Selection - Select (Triggering unit) for Player 9 (Gray)
        Trigger - Run Restart limit <gen> (checking conditions)
        Trigger - Turn off (This trigger)

Restart limit
    Events
    Conditions
    Actions
        Wait 0.01 seconds
        Trigger - Turn on limit building Red <gen>

Thanks for all the help though.
