C

I decided to make a storyboard. If you don't know what that is, It's a story that let's you makes choices, and changes based on your choices.

#include <stdio.h>

int main(void) 
   {
   char characterName[100];
   int aa;
   printf("Hello. This code will write a story, based on your choice.\n");
   printf("What is the name of your character?\n");
   scanf("%s",characterName);
   printf("Your name is %s",characterName);
   printf("\n");
   printf("One day, you encounter a portal. Do you enter it %s", characterName);
   printf("?");
   printf("Enter 1 to enter it, 2 for staying");
   scanf("%i",&aa);
  if (aa == 1);
   {
   printf("You chose to stay. END OF STORY.");
   }
   if (aa == 2);
   {
     printf("You step towards the bright, purple portal.\n It looks like a swirly mirror. You are entranced as you step forward, step after step. Adventures await you.");
   }
   return 0;
   }

What I have tried:

I need help please. Can someone tell me what I am doing wrong? I know the If statement is correct, it's a error somewhere else in the code.
