GLSL Shader Little Problem

Hello, I’m trying to get a GLSL shader going to see how it works exactly and to probably attempt writing and understanding the script later on. But I got the script ready, but when I render it it tries to render it but I get just the shadow produced by the script not the actual indentions from the script on the cube.

Any help is appreciated.
