Splitting a Matrix of Linked Lists

I'm almost positive that this should work, I'm just having some difficulty adding the nodes to the new lists..

I'm calling the split function in main in a loop

Code:

for(r = 0; r < matrix->rows; r++)
            split(matrix->m[r], &list_1, &list_2, r);

Here is the split function

Code:

void split (NODE *pList, NODE **list_1, NODE **list_2, int n)
{
    int count;
    NODE *pWalk;
        
    count = 0;
    pWalk = pList;
    while(pWalk != NULL)
    {
        //printf("%d", pWalk->data);
        //printf("(%d)", count);
        //printf("r = %d     ", n);
        if(n <= count)
        {
            //add to list_1
        }
        else
        {
            //add to list_2
        }
        
        pWalk = pWalk->link;
        count++;
    }
    //printf("\n");
    return;
}
