I would like a validation message to pop with Users Input displayed with the message

I am learning microflow functionalities , I already prepared a validation message to pop up if the character in the text box is more than 20, I want to make the message display the users input and say it is above 20 character. How do I do  it using microflow, is there any expression i could use?

Hi Naveen, you could use the ‘length($object/attribute) > 20 ’ in a split action in a microflow to determine if you need to show the validation message or not.

Alternatively you can use the default settings on the textarea to predetermine the lengt of the input and feedback to the user. This way you possibly don't need the microflow and the users gets the feedback directly. Also see https://docs.mendix.com/refguide/text-area
