'Configurable product' is losing currency format after choosing an option on dropdown menu

Question

everyone.

The product's price is shown correctly, format and currency symbol. But when I choose an option from the dropdown, the price loses format and the symbol disappears. Does anyone here has seen this issue? How to fix it?

Example: http://coletivix.com/t-shirt.html

Magento version: 1.8.1.0

Answer 1

I found what was causing the problem. The field (System > Configuration > General > Currency Setup

Custom Currency Format) was filled and probably it resulted in a conflict some how. Letting it empty solved my problem.

Answer 2

Soem body was change in confiriuable.js or Configurable.php(app/code/core/mage/catalog/block/product/view/type/configuarble.php) Please replace by default magento code
