[Plugin: HL Twitter] Pass tweetID using php

I’m trying to use

hl_twitter_display_widget(5,'425860927');

but it doesn’t work (425860927 is the id of the twitter user). How do I use it like this?

I tried to amend functions.php to take a Twitter user name as it makes more sense but that only changed the View more tweets link to the username ; my amended function is/ was

if(is_string($twitter_user_id)){
		//get tweets by name
			$user = $wpdb->get_row($wpdb->prepare('
				SELECT twitter_user_id, screen_name, name, num_friends, num_followers, num_tweets, registered, url, description, location, avatar
				FROM '.HL_TWITTER_DB_PREFIX.'users
				WHERE screen_name=%s
				LIMIT 1
			', $twitter_user_id));
			$single_user = ($wpdb->num_rows==1) ? true : false;
			if($single_user) $query_args['twitteruserid'] = $user->twitter_user_id;
			echo $user->twitter_user_id;
		}else{

and then the normal code on the other side of the if..else. followed by

//if($single_user) $query_args['twitteruserid'] = $twitter_user_id;
	$query = hl_twitter_build_tweets_query_object($query_args);

Any ideas how make this work?

Thanks.
