Hide a Custom Tab with no information on Product Page

[APSwebmaster]

I have successfully added a tab to my view.phtml page located at app/design/frontend/enterprise/aps/template/catalog/product.

I tried an if statement to hide it if the Specifications field is empty, i.e. no content. The issue is, it doesn't work. It still shows the tab even if there is no content.

My code is below at the end of post.

2 Questions:

1. Am I taking the correct approach? Basically, I am making a tab to have an Expert Review tab. I originally was going to use a cms block, but figured purposing the Specifications field was easier, for one, but also I could ignore the tab if no content

2. Can you please help ?

Thanks so much and here is my code and I attached a screenshot of the empty tabs.
