Configurable product prices didn't change

Hi,
Configurable product prices in product page didn't change when I choose a product by attribute, before few days it worked normally.
Who knows where is a problem?

Have you installed extensions  Or make any customization into source ? Well, its difficult to say anything without looking your site. Please do paste more information, like error or what you did ?
