Importing Textures

[L i am]

I am trying to import textures into SU. I seem to be able to import the image but not the normal map into the materials, as SU only allows me to select one of the files for instance the Image or the Normals map but not both. Obviously I am not doing it correctly can anyone lead me in the right direction?
Cheers

Normal maps are not supported by SketchUp.
