Issue using data link in XML Publisher

Question

Dear All,
I am new to XML Publisher, for the first time trying data link concept in XML Publisher tool. The issue is very simple, I have two queries Q1(say it fetches sales_order_number, application_name ) and Q2 (say it fetches sales_order_number , error_number, error_description). And sales_order_number is passed as input using data link to Query Q2 from query Q1 and Q2 will retrive more than one row for a given sales_order_number.
Say for a given dept_name 1001 the output will be something similiar like
Q1:
SO# | Appl.Name
1001 | 'Invoice '
Q2:
SO# | Error.# | Error Desc
1001 | 1512 | No Data Found
1001 | 1513 | Invalid Entry
1001 | 2674 | Error while inserting the record
and the query which I have used in XML template goes like this
<dataQuery>
<sqlStatement name="Q1">
<![CDATA[select sales_order_number, application_name                 
                  from T1
                 where sales_order_number = :in_sales_order_num]]>
</sqlStatement>
<sqlStatement name="LINES">
<![CDATA[
select sales_order_number , error_number, error_description
from T2]]>
</sqlStatement>
<link name="Dummy_LINK" parentQuery="Q1" parentColumn="sales_order_number" childQuery="Q2" childColumn="sales_order_number" condition="="/>
</dataQuery>
<daraStructure/>
And the grouping is as follows
<group name="G_Q1" source="Q1">     
     <element name="sales_order_number" value="sales_order_number"/>
     <element name="application_name" value="application_name"/>     
<group name="G_Q2" source="Q2">
     <element name="sales_order_number" value="sales_order_number"/>
     <element name="error_number" value="error_number"/>
     <element name="error_description" value="error_description"/>     
</group>
</group>
And in the RTF template I have properly used <?for-each:G_Q1?> <?for-each:G_Q2?>- --
<?end for-each?><?end for-each?>
Ideally the header (Q1) should have one row and the lines (Q2) should have 3 rows. But the issue here is even Q1 produces 3 rows.
If in case Q2 has 4 records, then Q1 also plots 4 records in the report output. Hope I am explaining the issue correctly. Any help to resolve the issue would be a great. Thanks in advance.

Antony.

try like this
<?if: (TYPE='A') or (TYPE= 'B')?><TABLE STRUCTURE><?end if?>
or
<?if:contains('A~B', TYPE )?><TABLE STRUCTURE> <?end if?>
