Hi All,
Does anybody know how can I count the values returned by a lookup formula?
I have a lookup in Nintex Form that returns duplicated values from a list, so its an array of value.
Example: Lookup returns:
[1;#Training A,1;#Training A] |
I would like to count the number of duplicate values returned so in this example it would "2".
My goal is to count how many people were applying for a particular training and not allowing the class number to grow over the limit. It would be good if I can prompt them while in the form, so I prefer a no workflow solution if possible.
