Get first name of person- Weird error

[simon66]

Hey im writing a program that a user inputs a list of first names and when they type stop, the names will output in alphabetical order. This is my code

code:

%This program will output last name fist var firstname:string var reply:string:="" loop put "What is your first name? Type stop to close program!" get firstname exit when firstname="stop" if firstname (1) > reply then firstname := reply end if end loop put "The alphabetically last name is ", firstname

What is wrong here?

firstname has to be an array of string, and you need a sorting algorithm. Look up bubble sort on wiki.
