Camera Projection Problem (tondc)

[realer]

Hello

after searching the forum i came to do this shader.. which should let me select a camera to project from and a map to project..

#pragma hint map image
#pragma hint cam oppath "obj/camera"

surface
GR_camera_projection_map(
string map = "";
string cam = "";
)

{

float uu,vv;
vector pos;

if (map != "")
{
if (cam != "")
{

pos = wo_space(P);

pos = toNDC(cam, pos);


uu = pos.x;
vv = pos.y;


Cf = texture(map, uu,vv);
}

else
{
Cf = {0,1,0};
//Cf = texture(map, uv.x,uv.y); // Debug purposes
}
}

else
{
Cf = {1,0,0};
//Cf = texture(map, uv.x,uv.y); // Debug purposes
}
}

now when i compile this in H9 0 720 i get no interface at all, bracing error and it simply does not work... what am i doing wrong?? light projection would work i know but i want it this way. also i need projection since uv-mapping creates awefull distortions and even more i want to understand vex shader programming ;
