Download file from grid

Hi,

I created a field in my form. The data type is “Document (File Name)”. It is a multi-upload.

I have a grid, and I want to let the user able to directly open or download the attached from one of the column in the grid.
Q1: I tried to create a new field in the grid and select data type as [LEFT]“Document (File Name)” but it does not work.

Q2: From the form, when i click the attachment. How can i allow the attachment to open directly instead of download.

Thanks.[/LEFT]
