I'm new to Nintex and browsing on this site I don't find any Nintex-produced guide on syntax for validation rules on user input.
In my case I would simply like to check if the input of a field matches:
yy = year (e.g. 15) must be between 10 and 16
mm = month (e.g. 03)
### = number of 3 digits
full lenght of string must be 8 digits starting with E
E1503001 is a valid input
If you can show me where to find syntax to build this kind of rules I can handle myself.
And an extension of this question: where are the in-depth reference guides of Nintex?
