form formatting all messed up

i have this problem quite a bit.
it seems every time i use a theme that i create on my own .. or download for that matter, and “press it” using

<?/* Template Name: name */?>,
<?php wp_head(); ?>,
<?php wp_footer(); ?>..

and the rest..

the formatting of any form i put on the site always messes up!
