Tower Defense Blocking

[Isthisnametaken]

I am making a tower defense, and I have a problem. When you block, the creep do not do anything. I then made a trigger
function Trig_Untitled_Trigger_001_Actions takes nothing returns nothing
call IssuePointOrderLocBJ( GetTriggerUnit(), "attack", GetRectCenter(GetPlayableMapRect()) )
endfunction

//===========================================================================
function InitTrig_Untitled_Trigger_001 takes nothing returns nothing
set gg_trg_Untitled_Trigger_001 = CreateTrigger( )
call TriggerRegisterPlayerUnitEventSimple( gg_trg_Untitled_Trigger_001, Player(11), EVENT_PLAYER_UNIT_ISSUED_ORDER )
call TriggerAddAction( gg_trg_Untitled_Trigger_001, function Trig_Untitled_Trigger_001_Actions )
endfunction

This did nothing. Lastly, since I based the levels off of the Peasant unit (I removed the worker classification), I made the first level Footman, but still nothing. I am extremely confused with this...

Open a TD / maul that when unit block they attack.

I found out what was wrong! I made a trigger that every 0.1 seconds to order all units owned by player 12 to move to a region, so the creeps didn't have time to attack. I removed the trigger, and everything is fine.
