Yes... there is a little trick I came up with that you can use to filter one recordset with the value from another.
It won't work if you try to set a recordset parameter run-time value directly to a row in a previously created recordset... so what you can do is create a fake $_POST field and then set it to the recordset row in the code.
So say that you want to create a recordset parameter in Recordset2 and have it set to $row_Recordset1['fieldname']... instead in the DW recordset server behavior you set the run-time value to $_POST['Recordset1_fieldname'] and then in the code you manually add:
$_POST['Recordset1_fieldname'] = $row_Recordset1['fieldname'];
Just above the Recordset2 parameter reference (inside the repeat region). That will allow you to filter one recordset with the value from another as if it was filtered by a posted form value.
