[SOLVED] Display Custom Fields and Values Under Post Heading

Hi all -

I hope that one of you can help me. I am using the custom fields in my posts. I want to list the values under the heading of the post, but only if the values are filled out. I have looked at the wordpress forum and this one and have read the "get meta data" and get custom post" functions and have looked for an appropriate plug in, but I'm not sure what php language or html language to use and in which of the Atatualpa pages to insert it into. I've been looking for hours.

thanks so much for your help.
