Downloadable product with different size Magento 1.9
Hi I am developing website using Magento 1.9.
From my site user can download some product. I need to give the options for different size dropdown before user download ( 3ft, 5ft or 10ft etc). I have tried configurable product concept ( downloadable product) with size attribute. But in frontend I am getting out of stock. when i check child product inventory, qty>0 and stock availability - in stock
