twitter oAuth for developers wordpress - can't output tweets - php

Question

I am using a great script called twitter oAuth for developers to create a twitter feed plugin for my wordpress site. The aim is to create a widget where the user can enter their username and number of tweets to display, and that shows in the clients site.
Twitter oAuth for developers creates the following function that is used to display tweets:
getTweets($number_of_tweets, $twitter_screenname_to_load);
Since I am allowing the user to change the username and no. of tweets, I have changed it to this:
$no_of_tweets = $widget['no_of_tweets'];
$twitter_username = $widget['twitter_username'];
$tweets = getTweets($no_of_tweets, ''.$twitter_username.'');
Where $widget['no_of_tweets'] and $widget['twitter_username'] are parameters specified by the user.
I have set defaults for this plugin as follows:
/* Setup Widget Defaults */
$this->defaults = array (
...
'twitter_username' => 'skizzar_sites',
'no_of_tweets' => 3,
...
)
);
So when I load up my plugin, it shows the latest 3 tweets from skizzar_sites - as it should. However, when the user change the number or username, the widget outputs a single random tweet from a random user.
Is there something obviously wrong with the way I have written the function:
$tweets = getTweets($no_of_tweets, ''.$twitter_username.'');
Here is my full widget code for reference:

Answer 1

Aha! Just figured this out - remembered from a few years back having a similar problem and it was because the no_of_tweets and _username paramteres in the function are documented the wrong way round.
Instead of
getTweets($number_of_tweets, $twitter_screenname_to_load);
its:
getTweets($twitter_screenname_to_load, $number_of_tweets);
