[Trigger] Trigger Refuses to Work

[Knight7770]

I have a trigger that is supposed to replace a space unit with a space unit that doesn't have any abilities if a unit that can attack is on it. However, it replaces all of the spaces on the board, which is not supposed to happen.
Here is the trigger:

• Monster Space
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Move
  • Actions
    • For each (Integer A) from 1 to NumberofSpaces, do (Actions)
      • Loop - Actions
        • Set OtherPoint = (Position of FriendlySpaces[(Integer A)])
        • Set OtherUnitGroup = (Units within 50.00 of OtherPoint matching (((Matching unit) is Able to attack ground units) Equal to True))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • And - All (Conditions) are true
              • Conditions
                • (Unit-type of FriendlySpaces[(Integer A)]) Equal to Space (Big)(No Move)
                • (Number of units in OtherUnitGroup) Less than 1
          • Then - Actions
            • Unit - Replace FriendlySpaces[(Integer A)] with a Space (Big)(Move) using The old unit's relative life and mana
            • Set FriendlySpaces[(Integer A)] = (Last replaced unit)
            • Animation - Change FriendlySpaces[(Integer A)]'s vertex coloring to (100.00%, 100.00%, 100.00%) with 100.00% transparency
            • Unit - Change ownership of FriendlySpaces[(Integer A)] to Player 1 (Red) and Retain color
          • Else - Actions
            • Unit - Replace FriendlySpaces[(Integer A)] with a Space (Big)(No Move) using The old unit's relative life and mana
            • Set FriendlySpaces[(Integer A)] = (Last replaced unit)
            • Custom script: call RemoveLocation(udg_Point)
            • Custom script: call DestroyGroup(udg_UnitGroup)
    • For each (Integer A) from 1 to NumberofSpaces, do (Actions)
      • Loop - Actions
        • Set OtherPoint = (Position of FriendlySpaces[(Integer A)])
        • Set OtherUnitGroup = (Units within 50.00 of OtherPoint matching (((Matching unit) is Able to attack ground units) Equal to True))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • And - All (Conditions) are true
              • Conditions
                • (Unit-type of FriendlySpaces[(Integer A)]) Equal to Space (Small)(No Move)
                • (Number of units in OtherUnitGroup) Less than 1
          • Then - Actions
            • Unit - Replace FriendlySpaces[(Integer A)] with a Space (Small)(Move) using The old unit's relative life and mana
            • Set FriendlySpaces[(Integer A)] = (Last replaced unit)
            • Animation - Change FriendlySpaces[(Integer A)]'s vertex coloring to (100.00%, 100.00%, 100.00%) with 100.00% transparency
            • Unit - Change ownership of FriendlySpaces[(Integer A)] to Player 1 (Red) and Retain color
          • Else - Actions
            • Unit - Replace FriendlySpaces[(Integer A)] with a Space (Small)(No Move) using The old unit's relative life and mana
            • Set FriendlySpaces[(Integer A)] = (Last replaced unit)
            • Unit - Change ownership of FriendlySpaces[(Integer A)] to Player 1 (Red) and Retain color
            • Custom script: call RemoveLocation(udg_Point)
            • Custom script: call DestroyGroup(udg_UnitGroup)

Thanks in advance
