Dear All,
Good day,
I am using weeknum() function to get week number. But, there is a
difference between the computer generated weeknum and what is shown on a real
calendar. Example, today is week 41 by weeknum(), but the calendar shows
week 40 (3 ~ 9 Oct). Why? Please...

On excel, if I enter a number on a cell it should calculate the product,
i.e. in a cell the value is 1000 (constant) and when I enter 5 it should
should automatically give 5000, if i enter 10, the result must be 10,000..
Is there any function or any manipulation method please...thanks
