I have modified my showcat.tmpl, and am showing 2 of the extra fields in my display...
See example

However, I have defined the following, but it is not showing the extra field names... I'm pretty sure this should be right, but is not showing the custom field name...
echo<<<PPPRINT
<td class="{$Style['menubar']}" align="center">
<span class="{$Style['medium']}"><b>{$Globals['extra1name']}</b></span>
</td>
PPPRINT;
