Sorting a Linked List

[cannsyl]

Ok I am trying to sort a linked list and I have declared

private:
      struct SongNode
      {
             Song s;                  //value in this node
             SongNode *next;          //cursor points to where the node is 
                                      //positioned
      
                         
      };
      
      SongNode *head;                 //points to the begining
      static const int MAX_MEMORY = 256;       //most memory allowed

and used

void BobCatPod::sort( )
{
     SongNode *i;
     SongNode *i_n;
     SongNode *j;
     SongNode *temp;
     
     if (head == NULL)
     {
           return;
     }
     j = head;
     while (j -> next != NULL)
     {
           j = j-> next;
     }
           while (j!= head)
           {
                 i = i_n =head;
                 while (i_n != j)
                 {
                       if (i_n-> next-> s < i_n-> s  )
                       {
                                  temp=i_n-> next;
                                  i_n-> next = temp-> next;
                                  temp-> next =i_n;
                                  if (i_n-> next = temp);
                                  else
                                  {
                                  next = temp;
                                  }
                       }
                                  i = i_n;
                                  i_n= i_n->next;
           }
                                  j=i;
     }
 
}

now in this line

else
                                  {
                                  next = temp;
                                  }

I get an error that says next is undeclared. Why???

[anon]

Does BobCatPod have a member called next?
