    Beginner!!!! Need Help!!! :confused:

    validate check for social insurance number.

    social insurance number: only 9 digits (1-9), only number, should be input in three boxes, 3 digit in each boxes( if possible use auto tab)

    add the odd digits : means 1th,3dr,5th,7th, 9th digits together = odd digits sum value

    Extract the even digits: mean 2nd, 4th, 6th, 8th digits-- and multiply by *2, add all the even digits together only if it is less than 10

    if the 2nd, 4th, 6th, 8th digits is greater than 10 then , add like this ( for eg the 4th digit is 18 then add= 1+8)

    Then,

    odd digits sum value + the even digit sum value = multiple of ten (%10)

    Welcome to the SP forums.

    This wouldn't be a homework assignment, would it?

    Code is Not Working!!!!
    Why? What is happening? An error? A wrong result? Could you explain a bit more?

    My calculation is perfect,
    I don't know how to put in three input boxes,
    There is something wrong with the function value and input function,
    If you have any time can you plz work on my code and post the correct one will be great!!!

    Thx for the response

    Please use the debug techniques of your web browser to learn about the problem that is occurring, and where.

    You will see something like the following:
    Uncaught TypeError: Object 123-456-789,123 has no method 'test'
