Why am I getting unexpected token 'else' ?

Hi, I don't understand why this code is not working as it seem to be the same of Dave's. The code works until here:

var inStock = [ 'apples', 'eggs', 'milk', 'cookies',
 'cheese', 'bread', 'lettuce', 'carrot', 'broccoli', 'pizza', 
'potato', 'crackers', 'onion', 'tofu', 'frozen dinner', 'cucumber'];
var search;

function print(message) {
  document.write( '<p>' + message + '</p>');
}


while(true){
 search = prompt("Search for a product in our store. 
Type 'list' to show all products and 'quit' to exit");
 search = search.toLowerCase();
 if (search === 'quit') {
  break

 } else if ( search === 'list'){
    print(inStock.join(', ')); 
   } else {
 if ( inStock.indexOf(search) > -1  );
   print('Yes, we have ' + search + ' in the store');
  } 
 }

but them, if I add the final 'else' :

else {
    print ( search + ' is not in stock.' );
  }

the prompt doesn't even run and appears a syntax error unexpected 'else'. This is the final code with the error:

var inStock = [ 'apples', 'eggs', 'milk', 'cookies', 'cheese', 'bread', 'lettuce', 'carrot', 'broccoli', 'pizza', 'potato', 'crackers', 'onion', 'tofu', 'frozen dinner', 'cucumber'];
var search;

function print(message) {
  document.write( '<p>' + message + '</p>');
}


while(true){
 search = prompt("Search for a product in our store. Type 'list' to show all products and 'quit' to exit");
 search = search.toLowerCase();
 if (search === 'quit') {
  break

 } else if ( search === 'list'){
    print(inStock.join(', ')); 
   }

else {
 if ( inStock.indexOf(search) > -1  );
   print('Yes, we have ' + search + ' in the store');
  } else {
    print ( search + ' is not in stock.' );
   }
  }
 }

Line 20, if ( inStock.indexOf(search) > -1 );

It looks like that open curly bracket should be there for the if statement instead of the semicolon
