Adding custom posts

Hi.
Am new to WP and yes i LOVE IT.. 🙂

I got the custom posts to appear in the post by adding the <?php the_meta(); ?> but after that am getting this:

key: a:22:{s:12:”productimage”;s:0:””;s:13:”productimage1″;s:0:””;s:13:”productimage2″;s:0:””;s:13:”productimage3″;s:0:””;s:13:”p

can anyone please tell me from where is this coming?? Please!!
