Nintex newbie here.
I am setting a string variable from a field in a list item. The field is optional, so I need to know whether the variable contains a value or not.
I am using a 'Run If' action to check the variable, but I only get options to check if the variable is 'equals' or 'not equals' to a value. There is no 'is empty' option.
I created another variable, and I am not setting a value to it, thereby leaving it null, and then I am comparing the two variables. It's not working, however.
Is there another way I can use to do this?
Many thanks in advance!
