inserting cgi script output into a page ??

Hi-

I'm sure someone out there knows how to do this..

I have purchased a zipcode dealer locater script (cgi) and
have it installed and working fine. When someone performs a
search they are taken to another page which shows the results
(output).

I want to place that output into a page that has my header and
footer so it looks like they have not left the page.

The script does not have a header/footer customization option..
otherwise I wouldn't be here.

How do you do this.....?

I also have the same problem with php scripts.

Any help is appreciated.

Thanks
