Bump Map, Specular and Shininess Shader

Hello all –

I'm currently trying to write a shader that will blend between two different textures, bump maps, and transparencies.

Unfortunately, it appears that while textures and transparencies are working, the bump maps are not.

Additionally, it doesn't appear that the specularlity is working, nor the shininess.

Does anyone have any suggestions?

Thanks!

 Shader "Bumped Specular Blend" {
 Properties {
     _Blend ("Blend Between Forward and Reverse", Range(0, 1) ) = 0
     //_Color ("Main Color", Color) = (1,1,1,1)
     _Transparency ("Transparency", Range(0, 1)) = 1
     _SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 0)
     _Shininess ("Shininess", Range (0.01, 1)) = 0.078125
     _MainTex ("Base (RGB) TransGloss (A)", 2D) = "white" {}
     _BumpMap ("Normalmap", 2D) = "bump" {}
     _BlendTex ("Blend (RGB)", 2D) = "black" {}
     _BlendBump ("Blend NormalMap", 2D) = "bump" {}
 }
