I want to know what's wrong with my project. there is code:

.data

Prompt: .asciiz " Please input a value for N = : "

Result: .asciiz " The sum of integers from 1 to N is: "

Bye: .asciiz " CS is not easy try harder."

JW: .asciiz " The number will truncated to integer: "

.globl main

.text

main:
