Sharepoint Data transfer

Hello everyone,
I am a bloody beginner and struggeling right now.I want to assgin the columns with their information to a variable so i can work with it. How do i do this?

@Charly-Moreno

on left of assign use the variable you want the data to be assigned to and on right use formula ListItem.Fields.Where(function(x) x.DisplayName.Equals("Display Name of Field"))(0).Value

but make sure because it is in loop the variable value would change for each iteration

cheers
