Hello,
I just discoverd that a datacard field is not the same as text input field in many regards.
How can I set the properties of a datacard field value that it has to me a number and only valid when its 8 digits?
If there are not 8 digits there can be a warning or visual remark to correct this.
I tried with len function but it never worked out. I hope someone can tell me what and where to put a function in it.
Thank you very much in advance.
Best.
