<script type="text/javascript">
/*
The code below will pop up an alert box
and ask you to guess the number, it will then
let user know if hot or cold and when you win it
will calculate the number of guesses it took the user to get to the answer
*/
var random_number = parseInt(Math.random() * 100, 10);
var guesses = 0;
var last_guess = 0;
var message = "";
var user_response ="yes";

while (user_response !="yes"){
user_response = prompt ("Do you want to play again?");
if (user_response == "yes") { HAVING A PROBLEM HERE !=CONTINUE GAME;
{ else if (user_response=="") { End Game Here ;
}

while (last_guess != random_number) {
guesses++;
if (last_guess == 0) >= (random_number - 20) && last_guess <= (random_number + 20)) {
message = "You're getting cold.";
} else {
message = "Ice Cold!";
}
last_guess = parseInt("0" + prompt(message, last_guess), 10);
}

message = "Success! You Win!\n";
if (guesses < 5) {
message += "You did an awesome job, it only took you " + guesses + " tries to guess the number!";
} else if (guesses <= 15) {
message += "Goodness. It took you " + guesses + " tries to guess the target number.";
} else {
message += "Yikes! It took you " + guesses + " tries to guess the target number.";
}
alert(message);
{

} // end if
} // end while

Code:

var user_response ="yes";
while (user_response !="yes"){
 	user_response = prompt ("Do you want to play again?");
	if (user_response == "yes") { HAVING A PROBLEM HERE !=CONTINUE GAME;
	{ else if (user_response=="") { End Game Here ; }

Simple answer is you just jump out while loop before it start.
To fix this problem is just change "yes" at var user_response to "no" or something else except "yes" and "".
