Hi Erin,
You can make your 5 mile circle into a donut and use that ring to select
the set of points you need. Make the table with the 5mi circle editable,
then select that object and do Object>Set Target. Then select the 2 mile
circle and do Object>Erase. Now you have the 2-5 mile donut you need and
can do a point-in-poly tool selection. That operation is a permanent edit
assuming you don't need the full 5mi circle anymore on its own.
Alternatively you could select points within the 5mi and NOT within the 2mi
via SQL.

Subject: MI Radius Question
I have a radius of 2 miles and all the volunteers within that radius. I
also have a radius of 5 miles and all the volunteers within that 5 mile
radius. What I want is a list of the volunteers that live in the 3 miles
between. In other words those people that are in the 5 mile group minus
the
people in the 2 mile group.
Ideas? Anyone? Would be very greatful and might even write in complete
sentences if I get the answer.
