I am new to Magento and I am using Magento ver. 184.108.40.206 community edition. My website was working fine before some days. I have added one custom option of Gift Wrap Requirement for Customers. For this I used Radio Button as you can see in below Image
After that, If we add to cart any Configurable product after selecting Size, then it gives error Please specify the product's option(s).
Thanks in Advance.
