Evaluating null variables

I think there is a need for improved evaluation of null values in variables, e.g. using a ISNULL() and IFNULL() type of functions. The currently available variable features and functions can be leveraged to create a much better user experience if conditions like "if ISNULL(variable) then display something else ...." can be dynamically evaluated. Of course one can write 'if variable = "" then ...' now but it is kludgy at best

    Hi Mallinath,

    You can use the following to check if a variable is null:

    IF ( [variable] =blank(), ..., ...)

    Best,
