If you use magento 1.9.3 version in your theme you need to add product_option.js go to your app/design/frontend/[Your package]/[Your default]/layout/catalog.xml

find catalog_product_view and in reference name="head" add this line

<action method="addJs"><script>varien/product_options.js</script></action>

its become like that:

<catalog_product_view translate="label">        
    <reference name="head">
      <action method="addJs"><script>varien/product_options.js</script></action>
    </reference>
<catalog_product_view translate="label">
