Hi I am trying to design a framework by creating a common function. what I want is to store the Aliases or name mapped variables in an excel and retreive it. Use them to pass as a common variable and perform an action like click or something.  when i store the aliases in a variable and pass to another function its not working, is there any way to achieve this.
