title: How can I use <source_model> for a textbox in Magento for system.xml?
body: <p>Because it's for a textbox, I'm not sure how the array is supposed to work.</p>
  
  <p><strong>This fails.</strong></p>
  
  <pre><code>public function getDefault_dailymatches()
  {
      return array(
        array('value' =&gt; 0, 'label' =&gt; Mage::helper()-&gt;__('First item')),
        array('value' =&gt; 1, 'label' =&gt; Mage::helper()-&gt;__('Second item')),
        array('value' =&gt; 2, 'label' =&gt; Mage::helper()-&gt;__('third item')),
       // and so on...
      );    
  }
  </code></pre>
  
  <p><strong>This also fails.</strong></p>
  
  <pre><code>public function getDefault_dailymatches()
  {
      $default = 100;
      return $default;
  }
  </code></pre>
