In your directory tree, goto sites/all/. In here you should have created a folder named modules and one named themes. Inside the themes folder, go into the folder of the theme you are using. The 'node.tpl.php' file should be in there.<br>
<br>If you have not made these folders, go ahead and do it. You can download a theme from <a href="http://drupal.org/project/Themes">http://drupal.org/project/Themes</a>, or copy one of the core themes from the themes folder. Then go to the admin page, under Site Build click themes. Change to a different theme, any theme will do, it will be changed again, then click save. Then select the theme you want to use, (the new theme or core theme from the site/all/theme folder), and save. Click the configure, and fix all your setting in here.<br>
<br>Now you are using the theme that is in you site/all/theme folder<br><br>To modify the 'node.tpl.php' of just that page, from your site root, go into modules/node and copy the 'node.tpl.php' and paste it into you theme folder in the site/all/theme/{your_theme} folder and name it using the file name that theme developer gave you. Modify the code as needed.<br>
<br>Make sure when you start a *.tpl.php that you try to find one to copy from the modules/ folder in the root. These are more likely to not to cause problems. Using theme *.tpl.php files could cause issues.<br><br>If you need more themeing help, <a href="http://www.lynda.com">www.lynda.com</a> has a Drupal Themeing title that is very good. Also <a href="http://www.mustardseedmedia.com/podcast">www.mustardseedmedia.com/podcast</a> is also good.<br>
<br>Hope that helps,<br><br>Cory<br><br><br>
