Welcome to The Scripts.

Sorry, but I can't help but think that this must be homework, especially with the formatting of the question. How far have you managed to get with this problem?

reads the same backward and forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a script that reads in a five-digit integer and determines whether it is a palindrome. If the number is not five digits long or is not a valid number, output XHTML text that displays an alert dialog indicating the problem to the user. Allow the user to enter a new value after dismissing the alert dialog. Continue the whole process until the user enters “stop”.

The experts on this site are more than happy to help you with your problems but they cannot do your assignment/program for you. Attempt the assignment/program yourself first and post questions regarding any difficulties you have or about a particular function of the code that you don't know how to achieve.

Please read the Posting Guidelines and particularly the Coursework Posting Guidlines.

Then when you are ready post a new question in this thread.
