Your sql is much too complicated and you didn't say what
content.location is related to. I'll assume you meat that a field
in content joins to tier1.t1id. Your sql would simply be:
select t1name, t2name, location
from tier1, tier2, content
where t1id = t1idfk
and t1id = some_field_in_content
to display it do this
<cfoutput query = "theOneAbove">
#t1name#<br />#t2name#<br />#location#<br
/>
