Miss Nancy, you mean sum of reflection and refraction right? These glass materials have no diffuse.
And if you do it as I did, by definition the sum is one. Why? Because I defined the refract amount to be 1 - the reflect amount.
So
refract = 1 - reflect
therefore
refract + reflect = 1

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
