Problems with "Vote it up" plugin

Hi,

I installe a plugin called vote it up .

It says: “You will need to insert the relevant code (<?php DisplayVotes(get_the_ID()); ?>) into the WordPress loop.”

I read from the wp forum about the loop (http://codex.wordpress.org/The_Loop) that “The Loop should be placed in index.php and in any other Templates used to display post information.” I’m using Arras theme and don’t know what other templates are used to display post information?

1. Where do I find the places to post this piece of code?

2. Do I add it in a random place in the text file?

3. It says in the wp Loop forum: “Be sure to include the call for the header Template at the top of your Theme’s Templates. If you are using The Loop inside your own design (and your own design is not a template), set WP_USE_THEMES to false.” Could someone explain this to me please?

Right now I added the code to single.php and not to index.php, because this is the contents of themes/arras/index.php http://imgur.com/VIOQA and nothing happened if I added the code there. Anyway, I seem to get the voting box next to my posts, but I cannot vote. Here http://imgur.com/WMaxF is what I did with voting buttons from the settings, they don’t function, they are only images.

Hope this isn’t too long. Thanks a lot to anyone bothering to answer, cheers!
