Go4Expert - Simple program but I am unsure how to fix it

I wonder if anyone can see where I'm going wrong? What I am trying to do is get a student name, get their two scores then it works out a grade (Pass,merit,fail) based on the addition of the two scores. Then it must loop 5 times to get 5 student names.

On the first loop everything works fine, but when it gets to the second it will display "Fail" no matter what combination of numbers I put in. Also it will not display the error message if I go over 50 (on the second attempt - works fine on the first)

I'm pretty new to this, so any helpful guidance would be greatly apprieciated :)

Code:

#include <stdio.h>

#include <conio.h>



void Welcome_Screen (void);

void score (void);

void Grade (void);





int i;

char name1[5][25], name2[5][25];

int score1[5], score2[5], answer[5];



main()

{



Welcome_Screen();

clrscr();







//This sets the counter to 0

i=0;



do

{



//Gets name and saves it

printf("\n\nPlease enter the students forename - ");

scanf("%c", name1[i]);

printf("Please enter the students surname - ");

scanf("%c", name2[i]);



score();



//increments the do loop by one until it has done it 5 times.

i++;

}

while (i<5);

clrscr();





getch();

return 0;

}

//-----------------------------------------------------------------

void Welcome_Screen (void)

{

//Displays a welcome message on initialisation

        printf("************************");

        printf("\n Student Grading System");

        printf("\n************************");

        printf("\n\n\n\n\n\n\nPress any key to continue...");



getch();

}

//------------------------------------------------------------------

void score (void)

{

 again:

//Gets first score and saves it

printf("Enter %c %c 's first score - ", name1[i], name2[i]);

scanf("%d", score1);

                                        if (score1[i] >50)

                       {

                   printf("The score must not be above 50");

                   goto again;

                  }





again2:

//Gets second score and saves it

printf("Enter %c %c 's second score - ", name1[i], name2[i]);

scanf("%d", score2);

                                        if (score2[i] >50)

                       {

                   printf("The score must not be above 50/n");

                   goto again2;

                  }

answer[i]= score1[i] + score2[i];

//calls the Grade function

Grade();



getch();

}

//------------------------------------------------------------------

void Grade (void)

{

        if (answer[i] <30)

                {

                printf("\nFinal grade for %c %c - Fail", name1[i], name2[i]);

      }

   else if (answer[i] <=60&& answer[i] >=30)

           {

      printf("\nFinal grade for %c %c - Pass", name1[i], name2[i]);

      }

   else

           {

      printf("\nFinal grade for %c %c - Merit", name1[i], name2[i]);

      }
