Creating a linked list while sorting it

Oh man! This stuff is giving me a headache! The concept is so simple, but I just can't seem to write the code. Can someone please show me how?

void createlistKB(Node * &First)
{
int NewID = 0;
cout << "Please Input Your List:\n";
cout << "Enter -999 to stop\n";
cout << "-----------------------\n";
Node *Temp1, *Temp2, *NewNode;
First = new Node;
cin >> First->ID;
First->Next=NULL;
Temp1 = First;
Temp2 = Temp1;
do
{
NewNode = new Node;
cin >> NewID;
if(NewID != -999)
{
NewNode->ID = NewID;
cout << First->Next;
if(NewNode->ID < First->ID)
{
NewNode->Next = First;
First = NewNode;
cout << First->Next->Next;
}
do
{
if(NewNode->ID < Temp1->ID)
{
Temp2->Next = NewNode;
NewNode->Next = Temp1;
}
Temp2 = Temp1;
Temp1 = Temp1->Next;
cout << Temp1->Next;
}while(Temp1->Next != NULL);



}
}while(NewID != -999);
cout << "THANK YOU!!!\n\n";
}



that's the junk i have so far, i can't seem to figure it out...

here is the Node:
struct Node
{
int ID;
Node *Next;
};

btw: I'm trying to sort it from lowest to highest. Thanks guys

It might be easier if you break the create list function up. Here's one solution, but it would be even clearer if my InsertNode function was broken up into functions to check for inserting before/after and whether Node has to go at the head of the list.

Code:

---

void InsertNode(Node* &First, Node* &toInsert)
{
    Node* Iterator = First;


    while(toInsert->ID>Iterator->ID&& Iterator->Next!=NULL)
        Iterator=Iterator->Next;

    if(toInsert->ID>Iterator->ID)  //Insert after Iterator
    {
        Node* Temp = Iterator->Next;
        Iterator->Next=toInsert;
        toInsert->Next=Temp;
    }
    else                            //Insert before Iterator
    {
        if(Iterator==First)
        {
            Node* Temp = First;
            First=toInsert;
            toInsert->Next=Temp;
            return;
        }

        Node* Prev = First;
       
        while(Prev->Next!=Iterator)
            Prev=Prev->Next;

        Prev->Next=toInsert;
        toInsert->Next=Iterator;
    }


}

       

void createlistKB(Node * &First)
{

    First = new Node;
    First->Next=NULL;
    cout << "Enter ID (999 to quit): ";
    cin >> First->ID;
    Node* Temp;

    for(;; )
    {
        int input=0;
        cout << "Enter ID(999 to quit):  ";
        cin>>input;
        if(input==999)break;

        Temp = new Node;
        Temp->ID=input;
        Temp->Next=NULL;
       
        InsertNode(First,Temp);
    }
}
