Required 2nd attachment control based on choice field (radio button) selection

Discussion created by mgreerzy on Jan 17, 2018

Hi everyone!  I've tried searching and couldn't find anything, so I'm posting.  I apologize if I missed this someplace else on the forums.


SharePoint 2013 using Nintex Forms.  I have multiple attachment controls.  One of the controls will be required no matter what, easy and done!  The second attachment control will only be required if they make a specific selection on a choice (radio button) field.  The controls will also be hidden unless the choice selection is made, also easy and done.


If I use the control settings to make it required, it is required even when hidden.  I can not for the life of me figure out how to create a validation function to make it required based on the choice field.


Any help is greatly appreciated.  Let me know if you need any additional information!
