Shader in Unity 4.6.3 have problems

I got a project with some error srcipts.

shader was fine.
but after I fixed up them
shader got some error, such as
1.function type parameters not allowed
2.syntax error, unexpected expecting or at token type name expected at token

It's seems a common problem, I encounted on them before, also could not fix
Could any one tell me what's wrong?

 

i guess need to see the shader code.. or at least the line where error seems to be.
