Walljump Sidescroller

[oblivion254]

Hi I have been searching around the forums and the web and found some walljump scripts and found myself finding a few errors if anyone could help me I would appreciate it.
C:\UDK\UDK-2012-05\Development\Src\Zero\Classes\ZeroPawn.uc(91) : Error, Bad or missing expression in Call to 'FaceRotation', parameter 2
C:\UDK\UDK-2012-05\Development\Src\Zero\Classes\UDNPlayerControlle r.uc(60) : Error, Bad or missing expression in parenthesis
checkjump function in my playercontroller

function CheckJumpOrDuck()
{
    if ( Pawn == None )
    {
        return;
    }
    if ( bDoubleJump && (bUpdating || ((EXILAcrobaticPawn(Pawn) != None) && UTPawn(Pawn).CanDoubleJump())) )
    {
        //UTPawn(Pawn).DoDoubleJump( bUpdating );
        if (maxJumpCount <= maxJumpLimitCurrent /*&& pIsInJumpVolume*/)
        {
            EXILAcrobaticPawn(Pawn).DoWallJump( bUpdating );
            maxJumpCount++;
        }
    }
    else if ( bPressedJump )
    {
        if (Pawn.Physics == PHYS_Falling)
        {
            if (maxJumpCount <= maxJumpLimitCurrent /*&& pIsInJumpVolume*/)
            {
                EXILAcrobaticPawn(Pawn).DoWallJump( bUpdating );
                maxJumpCount++;
            }
        }
        else
        {
            maxJumpCount = 0;
            EXILAcrobaticPawn(Pawn).AirControlReset();
            Pawn.DoJump( bUpdating );
        }
    }
    if ( Pawn.Physics != PHYS_Falling && Pawn.bCanCrouch )
    {
        // crouch if pressing duck
        Pawn.ShouldCrouch(bDuck != 0);
    }
}

walljump code in my pawn

function bool DoWallJump( bool bUpdating )
{
    local Vector HitLocation, HitNormal, End, Start;
    local Actor HitActor;
 
    //Perform trace
    Start = Location + (Vector(Rotation) * GetCollisionRadius()/2);
    End = Start + (vector(Rotation) * GetCollisionRadius() * 2.5);
    HitActor = Trace(HitLocation, HitNormal, End, Start, true,);
    `Log("Player try to jump on " @ HitActor);
 
    //check on what we want to jump, we jump only on world surfaces
    if (HitActor == WorldInfo || HitActor.isA('StaticMeshActor'))
    {
        `Log("-Player jump on the wall !");
 
        self.FaceRotation(rotator(HitNormal), GlobalDeltatime);
        Controller.SetRotation( rotator(HitNormal) );
 
        if( HitNormal.Y != 0)
            HitNormal.Y *= WallJumpBoostXY;
        else if(HitNormal.X != 0)
            HitNormal.X *= WallJumpBoostXY;
 
        Velocity = HitNormal;
 
        //PlayerController(Controller).PlaySound(playerSoundWallJump, false, true);
 
        Velocity.Z = JumpZ + WallJumpBoostZ;
 
        return true;
    }
 
    return false;
}
