wp-voting & montezuma

I've had mixed results using php-exec plugins to get wp-voting to show up on the index.php and single.php to work.

I was able to get the voting to work when I edited comments.php.

The problem with php-exec is two fold. One, My site allows users to submit stories, so I don't want registered users to be able to write php into the post. Second, php exec as a widget shows up on homepages/posts and I don't want users to vote on those sites.

Is there anything else I could do to ensure that this works.

Adding <?php if(function_exists('wpv_voting_display_vote'))
wpv_voting_display_vote(get_the_ID()); ?>

to single.php or index.php does not work from admin or from an edited file through ftp.

Thanks.
