Question : Create a Dlookup in a form based on three criteria’s in Access 2003

How to begin to create a Dlookup in a form based on three criteria’s.  
I want to base it on Effective Date, PlanType, and Plan (which is PCA, RS1, RS2, PP0).

I have a table with the following examples:
Effective Date PlanType       PCA      RS1      RS2       PP0
7/01/2010      Emp      100.00      150.00      175.00      275.00
7/01/2010      Emp +1      300.00      350.00      375.00      775.00
7/01/2010      Family      800.00      850.00      875.00      1075.00

I have combo boxes for Effective Date, PlanType and Plan. I want the Premium to be populated in the Rate field.
I have absolutely no clue as to how to even go about this. I know what I want to do in my head, but making it work! That is another story. So, if any one could assist, i would appreciate it.
Thanks in advance.
