Fix javascript errors in my store

My problems with this ecommerce javascript, an example:

[url removed, login to view]

The "PRODUCTS IN THE SAME CATEGORY" appear vertically, when really they should be displayed vertically.

The "quantidadet" button also does not work properly ..

These are indications that javascript has some errors.
