[Dev-C++] template usage

I'm having trouble using a template that i have.
I'm making a template class, and overloaded the comparison operator >.
The function below should compare the type of my class, with the template 
parameter T. I tested it with int as the type for the template and attempted 
to this comparison

basic_bignumber<int,0,9> value(15);
if( value > 3 )...
but the compiler complained and said there was no match for operator>
for value>3. Anyone have any ideas with whats wrong?

  template< typename T, int __low_value, int __high_value >
  bool basic_bignumber<T, __low_value, __high_value>::operator>( T& test )
  {
    basic_bignumber< T, __low_value, __high_value > compare( test );

    int pos1 = 0, pos2 = 0;

    for( int i = 0; i < value_size; i++ )
    {
      if( value[ i ] == 0 ) continue;
      pos1 = i;
      break;
    }

    for( int i = 0; i < compare.value_size; i++ )
    {
      if( compare.value[ i ] == 0 ) continue;
      pos2 = i;
      break;
    }

    if( pos1 == 0 && pos2 == 0 ) return false; //all were zero's

    else if( pos1 != 0 && pos2 == 0 ) return true; //if this had something
                                                   //while the other didn't

    else if ( pos1 == 0 && pos2 != 0 ) return false; //if this didn't have
                                                  //anything, while the 
other
                                                  //did

    //if the the total value_size - (pos+1) is then compare, there
    //are more values, so this would be greater...
    if( value_size-(pos1+1) > compare.value_size-(pos2+1) ) return true;

    //so if both the pos's are the same and the value's are both of
    //the same size...check each individual digit...
    bool greater = true;

    for( int i = pos1; i < value_size; i++ )
    {
      if( value[ i ] < compare.value[ i ] ) greater = false;
      else continue;
    }

    return greater;
  }
