PLEASE PLEASE HELP!

Sorry to shout but i desperately need help, and this forum said it closed my topic for a reason i don’t know.

But please tell me how do i turn this code below

<?php get_post(‘cat=47&showposts=12’); ?>

to getting the titles only from a certain catgegory. when i place that on the homepage it messes with my post and only get’s the post from that category.

I have a section on my homepage that i want to get post titles from a certain category but that codes make the whole homepage show post only from that category.
