So, the benefit of a template is that it standardizes one or more elements of multiple pages and makes it simple to control those elements. For example, suppose you had a banner you wanted to add to the top of 100 pages. Let's say you copy/paste the actual code for that banner at the top of 100 pages.

Now suppose a month later, you decide you don't like how the banner looks and you want to change it? In order to update the code, you now have to edit 100 pages and change the code on all of them!

Wouldn't it be nice if you had used a template instead? If you had placed the banner code into a template, and then placed the template on those 100 pages, all you would have to do is update a single page &mdash; the Template: page &mdash; and the changes would automatically propagate through all 100 of the pages that use that template.

Templates also have parameters that you can use to pass values. So for example, 2 different pages may use the same template, but with different values passed to the template that cause it to look slightly different on both pages. This is how infoboxes work.

In your case, it sounds like you have the actual code on all of the pages themselves. So yes, if that's the case, you will need to edit the code of all of those pages &mdash; there's no way around it. But, if you invest in templates now, it could save you this trouble from happening again in the future.
