Help - I am Never Satisfied!

As you may have noticed, I have lost the Titles to my Posts.
Last night I spent alot of time trying to add 'peek-a-boo' Posts to this Site to try to spruce up the look of things.
Instead, I lost the titles.
If anyone knows how to fix the HTML in the template for Minima Stretch I sure could use the help fixing it before I end up wrecking the whole Blog.
I like to change things around but sometimes I try to do things that I really am not experienced enough to do.
I did save my Template as the people who know about this stuff said but I didn't save it until I had already tried the Hack and it didn't work right.
I never learn and I am never satisfied!
