Create a web page that contains two text fields and a button labeled

Calculate. A user will enter his/her name and a number then click

Calculate button to get the result.

 Use JavaScript to:

1. validate the inputs:

 The name should contain only letters. If not, display alert

message “Not correct. Enter a valid name”

 The user should enter a correct number. If not, display alert

message “Not correct. Please enter a Number”,

1. calculate the result:

The result is the sum from 1 to the entered number. For example, if the

entered number is 3, the result will be 10 (1+2+3= 6). When the user

clicks the Calculate button, the result should be displayed in a new

browser window, and written in green color.
