Actually i don´t really understand wich values you are refering to.
But to get a glossy reflection just assign a vray material.
Set the reflection to white (or something) and set your glossiness
value to something below 1. That´s it.
If you want a specific material effect maybe a picture would be helpful.
Just turning on glossiness doesn´t mean it will look like
a carmetal shader immediately .. for example
This scene has way too much illumination on all objects. Too much will kill reflections ultimately. There are reflections on the wood and floor but is being attenuated by by the lighting.
