Problems With Tags PHP

Heyo!

So I have an theme from http://www.elegantthemes.com, and it didn’t come with a tag.php. I created a tag.php by copying my index.php and adding some additional code I found, and it almost works 😉 I have links on my sidebar that correspond to different tags on my blog posts. You can see what I’m talking about here : http://www.kylefitzgeraldphotography.com/show/ . The only problem is that when I click on a link for a tag, it only shows the most recent ones and there is no “older posts” or anything at the bottom of the page. And for some reason when I click on “Families” the sidebar disappears, but that is the only link that happens to, all the others keep the sidebar. Any help would be GREATLY appreciated! 🙂
