Setshape..o.O

[TeirDal_RC5]

Allrighty..
Here is my problem,
I can get this working:
setshape2 2,2,{3,3,3,3};
And I can change the tile type (the 3's) to whatever I need..
But if I change the width or height, it doesn't work any more?
For example:
setshape2 4,4,{3,3,3,3,3,3,3,3};
(Is that right?)
It doesn't really explain the way the tiletypes go for setshape2..
But anyhow, does anyone know why I am not able to set a different width and height for setshape?
