Errors not printing correctly..Is this logic flow correct? c++

Programmer Question

Example user input:

PA1 9 //correct 
PJ1 9 //wrong, error printed "Invalid row" because it is not between A and I 
PA11 9 //wrong, error printer "Invalid column" because it is not between 1 and 9.

The problem I am having is that it should clear the remaining input and then ask for the user to enter the "move" again, and it is not.

Where did I go wrong? I've been at it for a while and still got no progress..

void clearInput()
{ 
 cin.clear();
}

bool getCoords(int & x, int & y)
{
 char row;

 while(true){
 cin>>row>>y;
 row=toupper(row);

 if(/*(id=='P' || id=='p' || id=='D' || id=='d') &&  */row>='A' && row<='I' && isalpha(row)  && y>=1 && y<=9){ 
     x=row-'A';
  y=y-1; 
  return true;
 }

 else if(!(y>=1 && y<=9)){
  cout<<"Invalid column\n"<< endl << endl;
  cout<<y;
  clearInput();
  cout<<y;
  //return false; 
 }
 else{
  cout<<"Invalid row\n"<< endl << endl;
  clearInput(); 
  //cout<<x<<y;
  //return false;
 }
 }
}
