No worries Atpo the Fresnel group I used there is below

The Fresnel is the amount of Fresnel The F Power is the strength of that amount The specularity is how specular it is The EC and influence work on the roughness shininess and shadows etc of the fresnel effect. Basically this gives you a lot more control over the fresnel and its effects. Playing around with the sliders you'll get the idea of it. I tried to spread this out a bit so as you can read it a bit better.
