Texture Gone Wrong with TextureScale and TextureTranslations

[DeriLoko2]

I tried putting two models with textures. The problem is the eye. How can I figure that out? Maybe the part of the texture went inverted or something. Also, do TextureTranslations work on textures? Because if I do that, nothing really happened. If I put a big number in there, something happened. What am I supposed to do with the TextureScale? I did it right, did I?
