Sorry, I dont really get what your saying, could you be a little more descriptive?
If you mean the lines of the ramp you want them to match the lines of the nurbs surface then you might need to rotate the 2d placement node (that it looks like you might have disconnected) to suit the lines on the nurbs surface. Of it might be easier to map the texture.
Also watch the image sizes your posting the maximum allowed it 640 x 480.
