Oracle Forms

Hi,

I am using oracle form 10g and I just want to know, is there any way to access the URL parameters of oracle form on run time inside the form code.
I will illustrate the problem in depth.

For Instance :
I am having one form abc.fmb and when i compile it and run it. It will open in a browser with the following link

http://172.12.51.10:7778/forms/frmservlet?config=pkamble

Now I want to access or I want to perform some task based on the config part of the URL just after the '?' mark sign inside the code of abc.fmb

So I am curious to know any suggestion here from you seniors.

I had tried finding the same using the following block of code inside the abc.fmb on when-new-form-instance trigger

if (:PARAMETER.config = 'pkamble') then

message ('Hi Pkamble');

end if;

I am getting an error saying that Bad Bind variable 'PARAMETER.config '

Please suggest here.

I will appreciate the help !! :)
