Do I have too many Div Tags? Or too many Rows? Div Tags work only sometimes

I took an HTML class in High School, and that’s IT! So please be gentle, I’m looking for any help possible. I have a bunch of thumbnails that open to lightboxes here:

They’re formatted with Div tags, 200 pixels, into rows separating the type of video that people want to see. and as you can see, the last row isn’t behaving. I’m pretty sure it’s my code, but I’ve changed it and even re-written it and it seems to work only in the top 4 rows. The Div tags I put in the 5th row won’t work! Any ideas? Here’s the code:

[headline_arial_medium_centered color=”#000000″]Click on a video to see it play. It will open in a “LightBox” JUST like it will on YOUR Website![/headline_arial_medium_centered]
