the best place to get specific help for using the advanced recordset tab is the Dreamweaver help.
On the advanced recordset tab, click the help button to get the context sensitive help for the advanced recordset tab.
when creating an advanced recordset, there are three main ideas to keep in mind:
1) selecting column from your query to include in the where clause,
2) assigning a comparison operator
3) Create a Parameter to use in the comparison.
If you set filtering options using the simple recordset dialog, then switch to the advanced dialog, it will have created a parameter for you already that you can view as an example.
