error trying to get my first module to work...

Hi,
I want to test a simple form with some voting buttons.

I created a module called voteForm.module (code below) and voteForm.info.
I can successfully "enable" it in the admin->modules.

After that I get the following error:

warning: Cannot modify header information - headers already sent by (output started at /home/userc/public_html/sites/all/modules/voteForm/voteForm.module:57) in /home/brajeshc/public_html/includes/common.inc on line 311.

Can anyone see what I am doing wrong? thank you!
