I am having lots of trouble with one of my assignments. This keeps going in a continous loop and I cannot work out whats wrong. I am useless at coding and stuff. So any help is much appreciated.

<HTML>
<HEAD> Enter a number
<TITLE>Question 1 (ii)(a) </TITLE>
<SCRIPT LANGUAGE = "JavaScript" >

var userNumber;

var upperLimit = 20;

userNumber =
window.prompt('Please enter a number in the range 1 to ' + upperLimit, '');

userNumber = parseFloat(userNumber);

while (userNumber < 1 || userNumber > upperLimit)

{
UserNumber =
window.prompt('Please re-enter - number should be in range 1 to '
+ upperLimit, '');

userNumber = parseFloat(userNumber)
};

document.write('<BR>'+'Your chosen number was ' + userNumber)

</SCRIPT>
</HEAD>
<BODY>
</BODY>

</HTML>

JavaScript variables are case-sensitive, so you need to change the occurance of UserNumber to userNumber. Good luck.

Thank you.

I am so stupid. I have been staring at that for ages and trying to work out what I had done wrong. I hope that lots of helpful people are going to be around for a while. I have other problems as well.
