...more info instead of Add: on product listing page

On my Product listing page some products show ...more info and some show Add: [quantity]

It is not a truncating issue I don't think because the description can be as small as 3 words and show ...more but can be 15 words and show the Add: box.

Some of my product list pages do not show the "add selected products to cart" because all products in that category show ...more info instead of the Add: box.

This may be hard to understand so I am attaching a link to the store. Click on Bia Brasil under Shop by Brand and you will notice the top 2 have the the Add: box and the last product has ...more info. Check out other categories as well.

Any help is appreciated..Thanks

Any product that has attributes that need selecting will show "more info" as it can not be added without selecting the attribute

Thanks Kobra, you saved me a lot of headaches. I knew it was easy but couldn't see the forest for the trees.
