Problem while incrementing a variable in Jasper Reports

Question

Hi
I am using Jasper Reports for designing reports. These reports will be used by my Java application.
But there is problem while I am trying to increment a variable depending on some condition.
Requirement: I have to display information about all the residents in a hospital in a single report. Resident information will be fetched from the XML file. When a resident ID is found in the XML, then the variable(resno) shoud be incremented. I have set the initial value to 1.
Problem: Only for the first resident, resno is showing as 1. For all the remaining residents, its showing as 0 (zero).The variable 'resno' is not incrementing for each resident.
Even the ResidentID is not null. All the ResidentID's exists in the XML file.
Please find the code below.
<variable name="resno" class="java.lang.Integer" incrementType="Group" incrementGroup="residentbrk" calculation="Count">
<initialValueExpression><![CDATA[new Integer(1)]]></initialValueExpression>
</variable>
<group name="residentbrk" isStartNewPage="true">
<groupExpression><![CDATA[$F{ResidentID}]]></groupExpression>
<groupHeader>
<band height="16">
<textField hyperlinkType="None">
<reportElement positionType="Float" x="0" y="-1" width="96" height="17"/>
<textElement>
<font isBold="true"/>
</textElement>
<textFieldExpression class="java.lang.String"><![CDATA[$R{residentno}]]></textFieldExpression>
</textField>
<textField hyperlinkType="None">
<reportElement positionType="Float" x="96" y="-2" width="64" height="18"/>
<textElement/>
<textFieldExpression class="java.lang.Integer"><![CDATA[$V{resno}]]></textFieldExpression>
</textField>
</band>
</groupHeader>
</group>
Could you please provide a solution for this.

Not clear at all. May be like this
declare
v_temp varchar2(100);
v_final number;
begin
--loop
v_temp:='sun';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_temp := v_temp || 'Mon5.1';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_temp:= v_temp || 'Tue';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_final:=to_number(v_temp);
dbms_output.put_line('v_final'||v_final);
--coalesce
--end loop;
end;
