Maya - How do I disable the Alpha Channel?

Dibbz

I have a Lambert material with my TGA texture applied to my model but the Alpha is making it transparent. I use the Alpha to store a spec map but I don't want the diffuse to have the alpha channel applied. The transparency slider under the colour option is greyed out so I can't change it. Is there a way to disable the alpha in Maya?

right click on the word "transparency" in the attribute editor and select break connection.
also you can lock attribute in future if you dont want transparency to be pluged in automatically.

Thank you so much.
