In the end, the texture is supposed to look bumpy like this.
It looks just like that in the preview, but not when rendered. I've tried about everything I could think of, short of restarting the entire project from scratch. I've made about three textures the same way, but none of them seem to work. I even tried moving the object to another project in case it was something with the file. I am a complete noob and know almost nothing about this program. Here is how it looks like now, if that's be any help.
