Dynamic Variables

[Anon]

Maybe I'm a complete moron, but can somebody give me a reason why you would ever need to use dynamic variables? A real world example would greatly help too!

If I have a form asking for number of elements (n) and If I have to generate the next form asking what each of these variables values are then I can generate variable names dynamically,

element1, element2, element3....elementn etc. depending on n.
This is based on the practical application.
