Wordpress Plugin Development - What am I doing wrong

Question

What am I doing wrong....this doesnt seem to work... I keep getting the following error

Warning: Cannot modify header information - headers already sent by (output started at /home/puretige/public_html/wp-content/plugins/Pure Tiger/puretiger.php:13) in /home/puretige/public_html/wp-includes/option.php on line 568

Warning: Cannot modify header information - headers already sent by (output started at /home/puretige/public_html/wp-content/plugins/Pure Tiger/puretiger.php:13) in /home/puretige/public_html/wp-includes/option.php on line 569

The plugin generated 2 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

Please note I am very new to this....

Try removing the open close php tags before your plugin declaration.
