Hello, I'm trying to code a template for http://bungostraydogs.wikia.com/wiki/Chapters to create one for specific volumes. The code I am working on is http://bungostraydogs.wikia.com/wiki/Template:Volume on lines 12-14. I'm trying to create a specific if statement that will hide the second row with the release date and ISBN info if it is not input, but am having several issues with the code.

The row does not dissapear when the info is left blank and instead shows a black box, and when the info is filled out it creates bits of leftover code that shows up above the filled out template.

If anyone could teach me the proper code for this I would greatly appreciate it, thank you!
