Techno-tard question

Does anyone have any idea why the "hide-post/show-post" tags won't work if you have other links in your post? Well...sometimes it doesn't work. Sometimes it does.

I worked with my previous post until I was ready to throw the computer out the window and STILL could not get these friggin tags to work.

Do they get screwed up somehow if you cut, copy and paste them where you want them to go? Is it something I'm doing wrong, or is it some quirk in Blogger?
