Input data to a table using 2 variables

I have a table that is going to be receiving values but I don't know how to calculate where to input the data.
I couldn't upload via attachment so here is the link to fully understand the table I'm talking about - http://img841.imageshack.us/img841/3606/imagevu.png
The departments are identified on the upside and the months of the year on the left.

What is needed to know in order to calculate where the input will be:
Identification of month (probably using the function TODAY to keep it updated, I don't know how to do this)
AND
Department (which is already identified in cell D4 of Sheet1)

The information to input is at cell F8 in Sheet 1.

EDIT: Is this too confusing?
