Editable grid not working in mobile app

Hi Everyone,

I have a editable subgrid on the opportunity form for adding the poducts. We have added this grid using a web resource. We are able to add the products using this subgrid in the web application. But we cannot add products while using the mobile application in the grid.

When we click on the description, the lookup window for the products is not coming. Please Help.

Thanks

Aparna
