XML Question About Results Returned

Hi
I have created a page that gets job search results.
For this example: http://career-updates.org/kath.php?page=1&what=sales&where=florida&x=60&y=17
The totalresults returned is over 56K. However I only want 100 returned.

I have no idea how to only return 100 jobs results.

Thank you for helping me.

Kathy
