How to display only custom post types on a template page

Hi there,

I made some custom posts and i want to display them with a page template. So I have to place a query_post (‘post_type=custompost’) before the loop.

I copied a template, but i cant find the start of the loop, since it starts with a ‘global $post;’.

Needless to say, i am new to PHP. Is there any way i can define the ‘global $post;’ to a specific, custom post?
