THX -> but I am not familar with materials/effects - so pleace help me!

I tried this Code, but i have following Problems:

SED shows a Syntax-Error when running the script(i think it is not lite-c)

I want to move skin2 and skin3 in x-dircetion with using skill1 and skill2 -> how is it possible

How can i move the skin slower???

Code:
function mtl_UV_Clamp_event ();


MATERIAL* mtl_UV_Clamp =
{
	
   event = mtl_UV_Clamp_event;
	effect = "
		matrix matMtl;
		extern texture entSkin1;
		
		technique uvspeed
		{
			pass p0
			{
				Texture[1] = <entSkin1>;
				ColorOp[1] = SelectArg1;		
				TextureTransform[1] = <matMtl>;
				TextureTransformFlags[1] = Count2;
			}
		}";

}

function mtl_UV_Clamp_event ()
{
	mat_identity(mtl.matrix);
	mtl.ENABLE_RENDER = on;//<------------------ERROR Syntax???
	mtl.matrix31 = floatd(my.skill1, 1000);//how to change this to make it slower move?
	mtl.matrix32 = floatd(my.skill2, 1000);
}
