    Hi,

     

    Adding to the thread. If you want to check the JS variables, use this code:

     

    if (typeof yourVar === 'undefined') {
 
}

Thanks for that, I had figured out a way to do it...

 

The way I am using is..

 

if  ((!Emp_Num) || (!Start_Date) || (!End_Date))

{....}

 

this catches it, if one of the vars is missing....

    To be precise, this catches the situations when some variable is missed, or is null or is assigned a value that evaluates to false.

     

    To check for missed variable in JS Wamboo provided correct way of check.
