Its a little long winded...
Its based around a football league website premise...
I have a Teams table and a Fixtures table.
The Teams table has Team_ID column for each team, the fixtures table has a Hometeam_ID column and an Awayteam_ID column.
The problem I have is relating the Hometeam_ID and Awayteam_ID columns to the single Team_ID column!!
Access wont let me create a relationship between Team_ID and both Home/Awayteam_ID due to the name.
So I thought that if I create two new columns in the Teams table (Hometeam_ID, Awayteam_ID) and give them the same values as Team_ID it wouild solve the relationship problem!
