Please Help - No Alpha on Node material??

Hello Everyone,

I’m still working on understanding more about material nodes. I am unable to figure out why I cannot see thru a hole that has been via the dots plugin texture. I can see thru it fine when I use it on a material without nodes, but when I use it on a material with nodes, it doesn’t seem to work.

The attached images show the material setting for the normal material, and the material settings and nodes for the node based material. I will post a reply with a render.

Thanks in advance!
