Problem using Page items in trigger

Question

Hello all,
I have a requirement in my application in which I need to use a page item in my trigger..
My basic requiremtn is I have 2 forms to enter data..I need the name entered int he first form to be displayed in the second form, since am associating the data entered in the 2nd form to the name entered in the 1st form..
In my 2nd form where I need this, am setting the Source of Server_Name to P105_DEVICE_NAME. But I need this info to enter the details to the table..So I ve created the folowwing trigger.
create or replace TRIGGER "cts_apps_temp_insert"
BEFORE INSERT ON CTS_APPS_TEMP
FOR EACH ROW
DECLARE
vComputer_ID NUMBER;
vTemp varchar(200);
BEGIN
vTemp := :P105_DEVICE_NAME;
select computer_id into vComputer_ID from cts_hardware_info where computer_name = vtemp;
INSERT INTO CTS_SERVER_APP_CUSTOMER(SERVER_ID,DEPT_APP_REL_ID,TECHNICAL_MANAGER,FUNCTIONAL,APPLICATION_COORDINATOR,MODIFYUSERID,DATEOFMODIFICATION)
VALUES (vComputer_ID,:NEW.DEP_APP_REL_ID,:NEW.TECHNICAL_MANAGER,:NEW.FUCNTIONAL_MANAGER,:NEW.APPLICATION_COORDINATOR,v('APP_USER'),sysdate);
END;
But am getting an error executing this
Compilation failed, line 5 (10:44:08) The line numbers associated with compilation errors are relative to the first BEGIN statement. This only affects the compilation of database triggers.
PLS-00049: bad bind variable 'P105_DEVICE_NAME'
Is there any other way to access the Page Items from the trigger?
Thanks,
Nehal

Thanks Tyson. I have changed it but I still get the same error.
For some reason, The value of P105_DEVICE_NAME is becoming null.
I tried executing the following in SQL workshop.
begin
dbms_output.put_line('skdjaldjakdjalkdj');
dbms_output.put_line(v('P105_DEVICE_NAME'));
end;
and got the following output
skdjaldjakdjalkdj
Statement processed.
0.00 seconds
It doesnt print anything for v('P105_DEVICE_NAME').
Any idea why this is happening?
Thanks,
Nehal
