Hi

I created a quick test.  Custom list with two additional columns:

• "Checkbox" - Yes/No column - Default No
• "Textbox" - Single Line of Text

Edited form in Nintex Forms

chose textbox control > add rule > validation

Condition:

and(Checkbox==true, isNullOrEmpty({Self}))

I have something similar, I don't know how achieve this task as I am new to this. Any help would be highly appreciated.

I have first checkbox as YES/NO (Name: NA), trying to create a rule where automatically all the options (Name:Options) below automatically go uncheck when somebody clicks on this first "Not Applicable". If it could hide all the below options after clearing that would be great but not requirement. Definitely clearing them out is requirement.

Is there anyone who can help me with this. Thank you.
