[rt-users] search display question

[prescott at wcoil.com]

Where do I look to figure how to do the following:
I have a custom field called account number.
I want to call a rt page to pull up all tickets that have the account 
number = to xxxx
I have created a search and saved it but it has the account number as part 
of the search.
that is to say, I put 16000 as the hard-coded account number.
Where should I look to figure out how to accomplish this.
**Note: I am calling the page from another system which is not rt.

Thanks for any pointers.
