How to write a menu using BASH script

Could anyone give me a hand. Need to write and interactive menu using bash script.
Basically the output should look like this:

1) option 1
2) option 2
3) option3

I looked into a manual on this but its not clear i need some sample code or something
Anyhelp welcome
thanks

I have attached a sample script.. Don't forget to give it executable permissions before you run it.
(chmod 744 or whatever you need)
