Insert function in php not working?

I created a home page and I have a header.php page. In the homepage I wanted to include Header.php so I did this

<?php

     include(Header.php);

?>

When I browse to my page I get the following error which you can also see in the image I have provided.

Warning: include(Headerphp) [function.include]; failed to open stream: No such file or directory in C:\xampp\htdocs\carnivorousflamingo.com\home.php on line 3

Warning: include() [function.include]; Failed opening 'Headerphp' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\carnivorousflamingo.com\Home.php on line 3

I have tried to code these ways to:

<?php

include(../Header.php);

?>

<?php

include(/Header.php);

?>

but neither of them worked either. I am using xampp, phpmyadmin, hosting with Apache.

my file name is correct and my extension is .php

but I still get the same error message.

The browser I was using was google chrome.
