I have a global transition in a workflow named 'Update Ticket' to which I have assigned a screen I built with custom fields to collect some data from the user. Using this data I have some scripts that I need to fire as post-functions. I have assigned the screen I built to the global transition but when I click on the 'Update Ticket' from a test issue, it just opens up a screen with a Comment field. Why is my screen not showing up? Have I missed something in my configurations? Appreciate any help!
