I made a pdf form in livecycle designer where different user need to give their approval in the form. I searched in google and found an example here (http://assuredynamics.com/index.php/portfolio/using-hash-keys-to-lock-objects/). I changed 3 username given with the form and added 3 more username (By using Form properties>variables).
My problem is that when I want to give approval with user 5 & 6, I am getting below image
Sometimes I am getting below image when I try to give approval with User 1 to 4.
Here is the link of the form
Can anyone please give an idea how to solve my problem.
