This is piggy backing off a prior post about validating an attachment control for illegal characters. (The specified item was not found. )
In the Nintex 2013 form (attached) I am calling a routine to validate if the attachments in the form contain any illegal characters. If so it will highlight said file and throw an alert to the user explaining the issue.
The problem is unless there are no other invalid controls the form will submit. I need to to set the form as invalid and all the other validation in the form needs to run as well.
