analytic App : validating the input/parameter values

[Alteryx_user_aK]

Hi,

I am working on the app where I need to capture text input and date as parameter(interface) with below validation

- for text box, it should be upper case and must be entered (Mandatory)

- for date, it should be less than today's date.

if the criteria is not matching then message should be displayed on screen

Please let me know how to achieve it.

Thanks in advance

Hi @Alteryx_user_aK use a Error Messeging tool from the Interface tool category to validate each of criteria. You probaly need two of them. They will Send a Error Messege which you can tailor and and stop processing. You can click Open Example to see how they work from the Tool bar menu.

Hello Joseph, I tried using error messaging tool but it is not working.

first I dragged down text box tool. then I connected it with Error message tool. in error message tool, I have added if condition like if isNull([#1]) then "True" else "false" endif. and in below window where it says the error message when the condition true, I added the message. but when I execute it with null value, I am not getting the error message.

Thanks
