can someone please help me with making this class

I wrote a program for linked list(I have included the insert routine)
this works fine.
======================================================

struct node
{
string Drname;
string phoneNo;
node *nxt;
};
node *start_ptr = NULL;
node *current;
int option = 0;

//sorted insert in list
void insert_node(string name, string phone)
{

node *temp, *prev ;
temp = new node;
prev = new node;
temp->Drname = name;
temp->phoneNo = phone;
temp->nxt = NULL;
prev->nxt = NULL;
if (start_ptr == NULL)
{
start_ptr = temp;
current = start_ptr;
}
else
{
temp=start_ptr;
prev=NULL;
if (temp->phoneNo < start_ptr->phoneNo)
{
temp->nxt = start_ptr;
start_ptr->nxt = NULL;
}
else
{
while((temp->nxt != NULL) && (temp->phoneNo < current->phoneNo))
{
prev->nxt = temp;
temp = temp -> nxt;
}
temp->nxt = current;
prev->nxt = temp;
}
}
cout<<current->Drname<<endl;
}
======================================================

PROBLEM is when I try to make a class for this
I have a mess and not sure why

class node
{
public:
string Drname;
string phoneNo;
node *nxt;


node()
{
Drname=NULL;
phoneNo=NULL;
nxt=NULL;
}

~node()
};

When I try to compile it says string Drname is not defined same with phoneNo

yep I am a noob and just learning but I can't understand if its syntax or stupid code.

thanks big time for any help
this is driving me crazy.
