You should declare the variable
Dim ----
public----
private---

Option explict will automatically take care of defining the 
respective data types by VBS itself instead of defining the 
data types expicpity..

hi param i think u r wrong in option explict. 
option implicit is according to u its correct

option explicit force you to declare a variable to avoid any mistakes in the script

normally when u misspell something in script it takes as a new variable

option explicit force you to declare a variable to avoid 
any mistakes in the script

normally when u try to use a variable which is not declared 
in script then it will through an error saying that 
variable not declared.

If you used Option Explicit on Top of your script then you 
must declare all the veriables.
