UploadFile And Read Value in interface from a process

Certified Senior Developer

I'm trying to load in a grid on interface an excel file content.

I use a file upload component, and on submitform button i use a "startprocess".

"OnSuccess" event i'm trying to get a PV that contains the parsed value, return null.

I have had a first problem that going to fail the process but i introduce a 1 second delay on a node and now the process end everytime successufully,

but i cant get that value in my interface.

With same sintax i'm trying to get a pv that i'm just passed like process parameter, so that variable (a simple number) i have successufully recovered, from the same process.
