Extracting data from subform in Zoho Creator

Extracting data from subform in Zoho Creator

Hi,

I have created a form in Zoho Creator where customers can place an order and also add designs that need to be printed on the item.

However, I am currently unable to retrieve data from a subform. Is there a way to achieve this? I would like to send the item numbers and other information to Zoho CRM.

The reason why I use a subform is because it give the possibility to put the fields in a grid and give the option to create several article rules. 

Besides that I would like to send the uploaded designs to Onedrive, but I haven't found a solution for that too. 

I look forward to your responses!
