Problem calling Procedure with parameter from Dynamic Page

Question

I received an error saying the Page not found
here's how to reproduce the error.
1. Create procedure in portal30 schema.
Create or Replace PROCEDURE PORTAL30.ADD_TWO_VALUES
v_one IN NUMBER,
v_two IN NUMBER,
v_result OUT NUMBER)
as
begin
v_result :=v_one+v_two;
end;
2. Create Dynamic Page with following code
<ORACLE>DECLARE
v_total NUMBER;
BEGIN
ADD_TWO_VALUES(:v_one,:v_two, v_total);
htp.p('The total is => ');
htp.p('<input type="TEXT" VALUE='||v_total||'>');
htp.para;
htp.anchor('http://<machine.domain:port#>/pls/portal30/PORTAL30.DYN_
ADD_TWO_VALUES.show_parms', 'Re-Execute Procedure');
END;</ORACLE>
3. I clicked on Customize Link and entered 2 numbers as values for v_one and v_two.
4. Got "The page cannot be found" error in I.E. or "The requested URL /pls/portal30/PORTAL30.DYN_SAMPLE_ADD.show was not found on this server." on Netscape
However when I subsitute "ADD_TWO_VALUES(:v_one,:v_two, v_total);" in the dynamic page for "ADD_TWO_VALUES(3,2, v_total);", it runs just fine.
What's wrong here? Can I not use a parameter from a dynamic page and call a procedure with it? Help is needed urgently and will be greatly appreciated.

Hi,
I tried with your code with few changes ,please try with them.
Create or Replace PROCEDURE <myschema>.ADD_TWO_VALUES
v_one IN NUMBER,
v_two IN NUMBER,
v_result OUT NUMBER)
as
begin
v_result :=v_one+v_two;
end;
I created the procedure in <mySchema> and granted that to <application_schema> and made some changes
<ORACLE>
DECLARE
v_total NUMBER;
BEGIN
<procedure_schema>.ADD_TWO_VALUES(:v_one,:v_two, v_total);
htp.p('The total is => ');
htp.p('<input type="TEXT" VALUE='||v_total||'>');
htp.para;
htp.anchor('http://<your_host>/pls/<portal_schema>/<application_schema>.DYN_FOR_OTN.SHOW_PARMS', 'Re-Execute Procedure');
END;
</ORACLE>
Hope this helps.
