This sounds exactly like a problem I had a few weeks ago and was helped. Like they were saying above me, try a Union query. Here is the instructions that was given to me and it worked perfectly. In your case instead of 3 queries you will need 13. Also, I had to use brackets [ ] around my qry titles for it to work.
"Do three separate queries, each with only one column.
Then do a fourth Union query to combine the three..
In the design view of the fourth query, do to Query -> SQL Specific -> Union.
The code would look something like this.
select * from qry31_90
union
select * from qry91_180
union
select * from qryOver180;
Search for Union if you need more help, but I think that should put you on the right track. The operation you want to perform is a Union.
hope this helps.

Just remeber 2 important things about union queries:
1) Each query that makes up the Union must have the same number of fields.
2) If you want to work with the data they must have the same data types also.
