Can you calculate the odds ratio for a 2X3 Chi Square?

I know technically you can do the calculation, but what I really want to know is does this give you any statistically relevent information that you can interpret, or does it just give numerical guff?

Also, can anybody confirm that you calculate the degrees of freedom for a chi square by multiplying the number of columns minus 1 and the number of rows minus 1, as I've been given alot of contrasting info.

Ill affirm the df statement. As for the OR, could you fill us in on what stat you are talking about when you say 'OR for the 2X3 table', there are several ways to get a pooled estimate like this.
