subdomain setting of PDE, Coefficient form for two variables

I wonder if you can help me with the setting of the PDE, Coefficient form for 2 variable please; as I search in your document for Comsol's book but it wasn't help enough; most of the information was for the setting for one variable, and I need to set it for 2 variable.
My questions are mainly about the subdomain setting of PDE, Coefficient form for two variables (please note that i am using Comsol 3.5a):
1- For the setting of diffusion coefficient (c) we can see that there are two rectangular to fill under each variable, may I know what these rectangular stand for. Are they for x and y direction for each variable?
2- For the convection coefficient (beta) we have also two rectangular to fill under each variable; in each of them there is two zeros that could be filled with value or expression; may I know what these two rectangular represent and what are the two zero stand for please.
3- For the Conservative flux source term (gamma), there are four rectangular to be fill, and the name of the variable is not shows, may I know what these 4 rectangular stand for please.
