How to prompt user for input and use input else where in batch file

I am very new to batch scripting. I am trying to prompt a user to "Enter
directory path containing files to be converted:". Once they enter that I
want to prompt them to "Enter directory path to save files to once
converted:". My code currently prompts the first question, but then closes
before the user can input anything.
