Help with material effect

I am making a simple effect, a texture is on top of other texture/shader and blending in with them multiply mode.
I have tried by fail .. Could anyone have done it please help. I have try to find in the manual but the effect manual is too bad!
My code
Code:

bmap bcube=<cube+6.tga>;

function mtl_envmap_view()
{
        mat_set(mtl.matrix,matViewInv);
        mtl.matrix41=0;
        mtl.matrix42=0;
        mtl.matrix43=0;
}

function mtl_envmap_init()
{
        bmap_to_cubemap(mtl.skin1);
        mtl.event=mtl_envmap_view;
        mtl.enable_view=on;
}

material mtl_envmap
{
        skin1=bcube;
        event=mtl_envmap_init;

        effect=
        "
                texture entSkin1;
                texture mtlSkin1;
                matrix matMtl;
                technique envmap
                {
                        pass p0
                        {
				                     Texture[0] = <entSkin1>;
				                     ColorArg1[0] = Texture; // stage 0 = skin texture
				                     ColorOp[0] = Modulate2x;
				                     ColorArg2[0] = Diffuse; // modulate by lighting
								}
                        pass p1                       
                        {
                                texture[0]=<entSkin1>;
                                texture[1]=<mtlSkin1>;

                                zWriteEnable=true;
                                alphaBlendEnable=false;

                                colorArg1[0]=Texture;
                                colorOp[0]=Modulate2x;
                                colorArg2[0]=Diffuse;

                                colorArg1[1]=Texture;
                                colorOp[1]=blendCurrentAlpha;


                                addressU[1]=Clamp;
                                addressV[1]=Clamp;
                                texCoordIndex[1]=cameraSpaceReflectionVector;
                                textureTransformFlags[1]=Count3;
                                textureTransform[1]=<matMtl>; // transform camera space back to world space
                        }
                }
        ";
}

This is the code of an enviroment cube map.. Now, I want to make a texture blend over the shader. I think I must write a new pass, blend with the existing pass, but do not know how to do ?

No one knows, please help a newbie

So bad, I still can not solve this problem

most of the keywords are case-sensitive afaik.
