Regeneration depending on terrain

[aider]

Hello! Im trying to make a passive ability for my Ent Lord, Batuan. Its named "Evergrowing", and it regenerate HP of Batuan every 2 second, as long as he is on grass terrain. However, if he step on dirt, rough dirt or blight, he will loose HP each 2 second. So with little knowledge of triggers etc. I made this:

• Batuan Blight Reduction Init
  • Events
    • Unit - A unit Sells a unit
  • Conditions
    • (Unit-type of (Sold unit)) Equal to Batuan
  • Actions
    • Set BatuanPosition = (Sold unit)
    • Trigger - Turn on Batuan Blight Reduction <gen>

• Batuan Blight Reduction
  • Events
    • Time - Every 2.00 seconds of game time
  • Conditions
  • Actions
    • Set BatuanPosition = (Triggering unit)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Terrain type at (Position of (Triggering unit))) Not equal to Lordaeron Summer - Grassy Dirt
        • (Terrain type at (Position of (Triggering unit))) Not equal to Lordaeron Summer - Grass
        • (Terrain type at (Position of (Triggering unit))) Not equal to Lordaeron Summer - Dark Grass
      • Then - Actions
        • Unit - Set life of (Triggering unit) to ((Life of (Triggering unit)) - (20.00 x 1.00))
      • Else - Actions
        • Unit - Set life of (Triggering unit) to ((Life of (Triggering unit)) + (20.00 x 1.00))

But it doesn't seem to store Batuan in the variable BatuanPosition

• Batuan Blight Reduction
  • Events
    • Time - Every 2.00 seconds of game time
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Terrain type at (Position of BatuanPosition)) Not equal to Lordaeron Summer - Grassy Dirt
        • (Terrain type at (Position of BatuanPosition)) Not equal to Lordaeron Summer - Grass
        • (Terrain type at (Position of BatuanPosition)) Not equal to Lordaeron Summer - Dark Grass
      • Then - Actions
        • Unit - Set life of BatuanPosition to ((Life of BatuanPosition) - (4.00 x 1.00))
      • Else - Actions
        • Unit - Set life of BatuanPosition to ((Life of BatuanPosition) + (4.00 x 1.00))
