Input Source is not detected in dropdown

Hi, I have saved an excel sheet with data. But when I perform a field configuration and set Action = Set Value, the Input Source field is not listing the excel file.
P.S: The web application is within a Excel Loop.

Could you please help?

Hi,

Once you add a excel loop activity and select the excel then post that you have to click on setting icon and configure column mapping with arguments of your choice. Only then the arguments will appear.

Thank you so much for your help.
