I took your advice and cleared out the diffuse node. I changed the MODULUS function to MIN as the MUTIPLY made the preview look either white or black. There is some grey in the transparency map and MIN seemed to perserve it. The shader now looks like what I attached. I'll post a render in a minute.

Thanks
