IMPORTANT: static pages doesn't show content

Hi everybody. I have this blog and i am having problem with the static pages. I used custom template. At first there was no problem but now when i try to make a static page, anything i write it just doesn't show up. The only thing that shows up is the title.

I was trying to change a lot of things and i am not a programmer so i must have scrud up something. The problem is that i don't know where to look to fix it.

If you have anything that will help me or guide me, just shoot it.

Thank you and sorry for my English.
