Enable the input field when user clicks on check box
I am new to Adobe Forms and need help from you guys.
Gone through sdn links but couldn't find the required solution.
We are sending a PDF Form to bussiness via mail.
1. User opens the pdf & when they clicks on check box then input field should be editable.
2.If they clicks on submit without entering the input field, then it should through Error message.
How to achieve these 2 issues.
