AJAX and Php not keeping values between my drop downs

PHP
3

Fixed the Query

it actually works it gives me Country, State and City. the value is correct but between each dropdowns it still gives
Undefined index: state in C:\xampp\htdocs\loginandout\testandlearnajax2.php on line 5 and
|Undefined index: country in C:\xampp\htdocs\loginandout\testandlearnajax2.php on line 4|

Also not sure how i can fix the matter you raised by saying only one of the two AJAX sends the to my PHP. pretty new to AJAX :(
<?php
include('dbconnection.php');

$country = $_GET["country"];
$state = $_GET["state"];

if($country!=""){

			$sql2 = "select * from states where country_id= '$country'";
			$result2 = mysqli_query($link11,$sql2);

			echo "<select id ='statedd' onChange='change_state()'>";
			
			while($row2=mysqli_fetch_array($result2)){

			echo "<option value= '$row2[id]'>"; echo $row2['name']; echo "</option>";


						}	
	echo "</select>";
		}
?>

<?php
if($state!=""){

			$sql3 = "select * from cities where stateid ='$state'";

			$result3 = mysqli_query($link11,$sql3);

			echo "<select id ='statedd' onChange='change_state()'>";

			while($row3=mysqli_fetch_array($result3)){

			echo "<option value= '$row3[id]'>"; echo $row3['name']; echo "</option>";


						}
		echo "</select>";
		}
?>
