How can I call one variable over other ?
I am trying to use CSV stream function to read a CSV file .I am iterating that stream over a for each loop .for starting the iteration I have given a container and have added the names of columns over which I want to iterate .I am able to do so .But in my application I want to generalize this loop for any CSV file with different column names , as I am using if else loops in for each loop for analysis .So for that I am trying to call a local variable over this container which I have created for iterating over this stream .But i am not able to do so ,its causing error as unknown variable ,is there any way to call one variable over other ?
