Anyone been having problems with scanf?

When using multiple scanf's in a program, only the input from the last
scanf is saved
in the varible.

My code works fine in Borland, but not in DJGPP!  What's wrong?

---Code---

#include <stdio.h>
#include <stdlib.h>

void main (void)
{
	unsigned short i;
	unsigned short k,l;
	unsigned short j;
	unsigned short remainder;
	unsigned long num_of_prime_numbers=0;
	signed char placeholder;
	printf("Enter the range of the prime numbers\n");



	scanf("%u",&k);

	scanf("%u",&j); /*In DJGPP, only 'j' is stored.  'k' is zero?  */


	printf("Prime numbers between %d ",k);
	printf("and %d.",j);

	for(i=k; i<j; i++)
	{
		placeholder=-1;
		for(l=2; l<i; l++)
		{
			remainder = i % l;

			if(remainder == 0)
				{
				placeholder=0;
				break;
				}


		}
		if(placeholder==-1)
			{
			printf("%d,",i);
			num_of_prime_numbers++;
			}
	}

	printf("\n\n\nTotal number of prime numbers in range:
%ld",num_of_prime_numbers);

	getch();
}
