Adding a left sidebar to the RedTime theme

I have been trying to get a left sidebar on my WordPress for a while and I sort of know nothing about PHP and CSS… What do I do in the RedTime theme to get this to work? I have added ` register_sidebar(array(‘name’=>’LeftSidebar’,
‘before_widget’ => ”,
‘after_widget’ => ”,
‘before_title’ => ‘<h2>’,
‘after_title’ => ‘</h2>’,
));`
in the functions.php file, and that is working fine – I have the second sidebar in the Widgets Admin panel, but I don’t know how to call it up… I saw that I should put it in index.php, but I once again, couldn’t find where.

Thanks in advance for the help…
