When a user visits this product, ( https://www.virginbrazilian.com/products/buy-2-get-1-free-13a-luxury-bundle-sale-limited-time-offer ) the free bundle options should be disabled by default. Upon selecting options from both bundle one and bundle two, the free bundle options should be enabled. The technical question is that the length for the free bundle should be set to the smallest length selected from bundle one and bundle two.
More Explain,
The actual lengths are 20, 22, 24, 26, 28, and 30. These lengths will be the same for bundle one, bundle two, and the free bundle. The condition is that the free bundle option should be enabled only when selections are made for both bundle one and bundle two. Additionally, the length for the free bundle should be set to the smallest length selected from bundle one and bundle two.
