OK. Firstly a fix for your immediate problem. If you don't already have one, create a directory called includes/templates/purpleshades/templates.
Then copy includes/templates/template_default/tpl_product_info_display.php into your new directory and open the new copy for editing.
Lines 158-159 should read> <td class="main" align="left" valign="top"><?php echo $options_name[$i] . ':'; ?></td>
<td class="main" align="left" valign="top" width="75%"><?php echo $options_menu[$i]; ?></td>Edit them to read> <td class="main" align="left" valign="top" width="60px"><?php echo $options_name[$i] . ':'; ?></td>
<td class="main" align="left" valign="top"><?php echo $options_menu[$i]; ?></td>Upload the new file to your server.
That will deal with your immediate problem, but you have a bigger one. Kobra is right. 1.3 is much better. It's architecture is superior, it's much more standards compliant, it has some snazzy new features, but most importantly for a online shop, it has some important security fixes.
It's a cheek for your webhost to say that they only support version 1.2.7. They are leaving you with an outdated, no-longer supported version of Zen Cart containing known security flaws. How can they can they call that support. I'd recommend looking for a new host. Some like Camelot-Hosting will even move your site for you, and the Purple Shades template is available for version 1.3 so upgrading shouldn't be too difficult.
