Please assist with the below. I received a response on what to fix, but I don't under. This is what was said:

"For task $1$:

your logic for this task needs some work, You can use the loop to find the index of the numbers and then try to swap the index of the last $2$ numbers.

For task $2$ when trying to click the submit button there is an error stating that checkPalindrome is not defined, please can you look into this.

I have also attached two links below that will help explain the for and while loops in more detail:"

Follow these steps:

Note: For this task, you will need to create an HTML file to get input from

a user. Refer to your previous learning material for a refresher if needed.

Create a new JavaScript file called swapping.js$.$

Write a program that asks the user to enter a number of at least $3$ digits.

Make use of a for loop to swap the second digit and last digit in the

number

Output the original number and the new number.

Compulsory Task $2$

Follow these steps:

Note: For this task, you will need to create an HTML file to get input from

a user. Refer to your previous learning material for a refresher if needed.

Create a JavaScript file called palindrome.js$.$
