  <p>The inputs are mutually exclusive, either you have an amount or a customamount.
  The doctype is HTML5.</p>
  
  <pre><code>&lt;div class="inputRow"&gt;
      &lt;input type="radio" name="amount" value="50" class="preset_amount" checked="checked" /&gt;
      &lt;label&gt;50&lt;/label&gt;            
      &lt;input type="radio" name="amount" value="100" class="preset_amount" /&gt;
      &lt;label&gt;100&lt;/label&gt;
      &lt;input type="radio" name="amount" value="150" class="preset_amount" /&gt;
      &lt;label&gt;150&lt;/label&gt;
  &lt;/div&gt;
  
  &lt;div class="inputRow"&gt;      
      &lt;input id="customamount" name="customamount" type="text" placeholder="&lt;?php echo _('custom amount') ?&gt;" &lt;?php getValue("customamount") ?&gt; /&gt;
      &lt;label for="customamount"&gt;&lt;?php echo _("or choose a custom amount") ?&gt;&lt;/label&gt;
  &lt;/div&gt;
  </code></pre>
