UV Set modification on an example shader?

Hi,
I dont know anything about shader programming, but I found a shader that does almost exactly what I need..
The only modifications that I need is that Texture 1 needs to use UV Set 0 and Texture 2 needs to use UV Set 1. I don't need an option to change that, it can be hard coded.
Hope anybody can help me out here.

Thanks!!

Code (CSharp):

1. Shader "Blend 2 Textures" {
2. Properties {
3.     _Blend ("Blend", Range (0, 1) ) = 0.5
4.     _MainTex ("Texture 1", 2D) = ""
5.     _Texture2 ("Texture 2", 2D) = ""
6. }
7. SubShader {  
8.     Pass {
9.         SetTexture[_MainTex]
10.         SetTexture[_Texture2] {
11.             ConstantColor (0,0,0, [_Blend])
12.             Combine texture Lerp(constant) previous
13.         }      
14.     }
15. }
16. }
17.
