I have been scratching my head at this all day

I cannot seem to figure out what's wrong with this class declaration.

#define MAXWORDS 30011
#include 
#include 


#ifndef _HASTTABLE_H
#define _HASHTABLE_H

class hashtable
{
public:
	hashtable();		// Default constructor
	class hashtable_item	
	{
	public:
		int scan_order;	        // Scanned in order
		int count;		// Occurnces
27:		string keyword;		// The actual string
	};
	hashtable_item table [MAXWORDS]; // An array of hashtable_items
	int size;		

32:	int f (const string&);	    // Hashing function
33:	void insert (const string&);// Inserts string into the hashtable_item
};

#endif

And I get the following errors:

------ Build started: Project: project2, Configuration: Debug Win32 ------

Compiling...
