Changes don't occur in index/header files

I am trying to change the "congrats you've installed zencart", the logo, and the "powered by zencart" following the descriptions in the FAQ section.

I've created my custom file in my English folder and have saved the files to this folder. I then moved the folder to the designated spot on filezilla and uploaded...

What next? I don't see my changes and it's been a few days.

To create a very basic custom template (you can build from there), you need:

• includes/languages/YOUR_TEMPLATE/english.php
• includes/languages/english/YOUR_TEMPLATE/index.php
• includes/languages/english/YOUR_TEMPLATE/header.php (to change the logo)
• includes/templates/YOUR_TEMPLATE/template_info.php
• includes/templates/YOUR_TEMPLATE/common/tpl_header.php
• includes/templates/YOUR_TEMPLATE/common/tpl_footer.php
• includes/templates/YOUR_TEMPLATE/images/logo.gif
• includes/templates/YOUR_TEMPLATE/css/stylesheet.css

Any where you see a /classic/ folder, you can create a folder for your custom template. Copy the files you need from /classic/, /template_default/ or the parent directory.

Edit includes/templates/YOUR_TEMPLATE/template_info.php to give your template identifying info (you'll understand when you open the file).

Always use a text editor like Notepad or Crimson Editor to edit php files.

Once you've built your template, go into your admin under tools->template selection and select it from the pull down menu.
