 If the data or description text for your custom track was originally loaded from a file on your hard

 using the &quot;Choose File&quot; button. Note that edits made on this page to description text uploaded

 <p>
 Browser lines configure the overall display of the Genome Browser window when your annotation file 
 is uploaded. Each line defines one display attribute. Browser lines consist of the format:</p>
 <p>
 <pre><code>browser attribute_name attribute_value(s)</code></pre>
 
 <p>
 For example, if the browser line <code>browser position chr22:1-20000</code> is included in the 
 annotation file, the Genome Browser window will initially display the first 20000 bases of chr 
 22.</p>
 <p>
 The following browser line attribute name/value options are available. The value
 <em>track_primary_table_name</em> must be set to the name of the primary table on which the
 track is based. To identify this table, open up the

-<h2>Track lines</h2>
+<h3>Track lines</h3>
 <p>
 Track lines define the display attributes for all lines in an annotation data set. If more than one 
 data set is included in the annotation file, each group of data must be preceded by a track line 
 that describes the display characteristics for that set of data. A track line begins with the word 
 <code>track</code>, followed by one or more <code>attribute=value</code> pairs. Unlike browser 
 lines - in which each attribute is defined on a separate line - all of the track attributes for a 
 given set of data are listed on one line <em>with no line breaks</em>. The inadvertent insertion of 
 a line break into a track line will generate an error when you attempt to upload the annotation 
 track into the Genome Browser.</p>

 The following track line attribute=value pairs are defined in the Genome Browser:</p>
 <ul> 
   <li>
   <strong>name=<<em>track_label</em>></strong> - Defines the track label that will be displayed to 
   the left of the track in the Genome Browser window, and also the label of the track control at the
