Calling a member function from C

["Lyte _" <opa_script@...>]

Hello!

I want to call a lua member function from C, and I can not get it to work. 
This is how I do it now.

 lua_getglobal(L, "IWindow");
 lua_getfield(L, -1, "new");
 lua_pushnumber(L, 100);
 lua_pushstring(L, "foo");
 if (lua_pcall(L, 2, 1, 0) != 0)
 {
   printf("\n%s", lua_tostring(L, -1));
 }

I have a class in lua called IWindow, and it has a member function called 
new. So I want to do IWindow:new(100,"foo") basicly. But for some strange 
reason, when I arrive in my function, the first parameter is "foo" and the 
second parameter is nil. So where has the number (100) gone? I'm sure the 
error is just something small, but I do not understand what it is...
