Relational DB Design

Hey all!

I'm new to relational db design and I've run into a problem. Here is the scenario:

I have a table that contains three fields (well, it contains more than that, but three of which this problem is concerned with). Each of these three fields can have one of two values. However, trying to keep data integrity and reduce redundant data, I am unable to relate these fields to a table.

Table1:
tblID <pk>
... <other fields>
Field1
Field2
Field3
... <other fields>

Table2
tbl2ID<pk>
Field4
Field5

The idea is that Field one can equal the contents of tbl2ID 1 or 2 (being the two possible values) as well as Field2 and 3. I've tried linking tables but it still doesn't produce a unique way for me to display the data in fields 1-3 in my code.

Is this as clear as mud?
