Add to Cart button not showing on product info page with attributes

[Harvard]

All of my other products show a qty box and add to cart button.
I have one product that has attributes, and there is no button or qty box.
Any suggestions?

When a product has attributes, the product-index page shows "more information ..." to direct the customer to the specific product's listing page.

On the Product listing page, there is no add to cart button. There is only one product in one category.

Sorry, it was a bit early when I posted previously ...

On the product listing page (main_page=index&cPath=xx), if a product has attributes 'More information...' is shown. If you view that product's specific info page (main_page=product_info&cPath=xx&products_id=yy) you "should" see the add-to-cart button.

Yeah that's the problem, I don't see it.... Any idea where I should look to find the solution?

EDIT: Just fixed it! There needed to be some kind of text in the product description. :)
