C++ namespace not declared but it is?

I'm having a compile time problem. New to C++ so I'm sure it's simple. I am gettign the current error.

diarydb.cpp: In function ‘bool editdate(int, mysqlpp::Connection&)’: diarydb.cpp:413:
error: ‘format_tests’ has not been declared

but diardby.cpp I have declared format_tests here

namespace format_tests {
  bool testdateformat(string &date);
  bool tesettimeformat(string &time);
  bool lengthcheck(string &in,int length);

}

with

bool format_tests::testdateformat(string &date){
  // tests format of dat input for MYSQL form at of YYYY-MM-DD
  // Need to tweak regex to restrict 0 < MM < 12 and 0 < DD <31.

  const boost::regex e("\\d{4}\\x2D\\d{2}\\x2D\\d{2}");
  return boost::regex_match(date,e);
}

the compiler compler of the call here.

  bool dbsetget::editdate(int e_id,mysqlpp::Connection &con){

        char evdate[11];

    cout << "Input start time" << endl;
    cin.getline(evdate,11,'\n'); // restrict legth of input with getline.lenght of input

    string date = evdate;

    if (format_tests::testdateformat(date)){
    mysqlpp::Query query = con.query();
    query <<"UPDATE main SET date="<< quote_only << date <<"WHERE d_Id ="<< e_id;

    return query.exec();
    }
    else
    {
      cerr << "Date not in correct format. YYYY-MM-DD ";
      return false;
    };
  }

I don't understand what the problem is? I have declared format_tests namespace Can anyone please guide me?

I'm sure there are plenty of to mistakes in here too but this one has got me pretty confused.

Looks like the file in which you have 

format_tests::testdateformat(date)

cannot see the 

namespace format_tests
{
     bool testdateformat(string &date);
};

Have you included the header file where the testdateformat is declaired?
