    else
        set curDist = 0
    endif
    loop
        set loopUnit = FirstOfGroup( g )
        exitwhen loopUnit == null
        set dX = x - GetUnitX( loopUnit )
        set dY = y - GetUnitY( loopUnit )
        set loopDist = SquareRoot( dX * dX + dY * dY )
        if loopDist < curDist == closest then
            set curDist = loopDist
            set curUnit = loopUnit
        endif
        call GroupRemoveUnit( g, loopUnit )
    endloop
    set ReturnHandle = curUnit
    set filter = null
    set loopUnit = null
    set curUnit = null
    return ReturnHandle
endfunction

to make it syntax, i had to make the global unit and group, but it loaded fine

fascinating. I double checked it and it didn't for me. Oh well...

EDIT:
Problem was ReturnHandle was a handle for me, not a unit : )
Thanks for helping to find the error!
