To select all the products belonging to a single member, coming from another page which passes on the m_id variable as the common field between the 2 tables:
<pre id=code><font face=courier size=2 id=code>
select * from table2 where m_id = MMColParam
</font id=code></pre id=code>
then you can specify the variable m_id as an HTTP_GET variable:
<pre id=code><font face=courier size=2 id=code>
Name Def Value Runtime Value
---------------------------------------------------------------------------------
MMColParam 0 $HTTP_GET_VARS["m_id"]
</font id=code></pre id=code>
just make sure you use a "Go to Detail page" link on the previous page to ensure the variable is correctly passed on....
I hope it helps.
