Variables!?

[Nihongoman]

Can somebody help me understand variables? Or just give an example how to use a variable? Thanks.

Example of variables:

If you talk to man X amound of times, then he does something different.  Instead of making thirty billion switches for all the times you have to talk to him, you can use a single variable and make it increase by one every time you talk to him.  Afterwards, make another page that has a requirement that Variable is set to X number.
