[JASS] Calling a function from a different trigger?

[ShadowPriest]

im trying to run a function from a different trigger.
this is my function to nudge a unit

function Nudge takes unit SlideUnit, real Distance returns nothing
    local real Facing = GetUnitFacing(SlideUnit)
    local location UnitPos = GetUnitLoc(SlideUnit)
    local location NewPos = PolarProjectionBJ(UnitPos, Distance, Facing)
    call SetUnitPositionLoc( SlideUnit, NewPos )
    call RemoveLocation(UnitPos)
    call RemoveLocation(NewPos)
endfunction
//===========================================================================
function InitTrig_Slide takes nothing returns nothing
    set gg_trg_Slide = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Slide, function Nudge )
endfunction

and this is the trigger im trying to get to run the function

• Slide Init
  • Events
    • Player - Player 1 (Red) types a chat message containing nudge as An exact match
  • Conditions
  • Actions
    • Custom script: call Nudge(gg_unit_hfoo_0000,10.00)

when i enable the trigger it says "Expected a function name". is there a way to get this function to run from this trigger?
please help me if you can.
