Panel Builder 6.0.3 Dynamic Alarm Text

Hello,

I am trying to configure alarm texts dynamically. I have a tag from the AC800M in string format that I would like to display when an alarm is active. I click on the three dots in the text box for the alarm "text" in Alarm Server and it opens the dialog. For {0}, I enter the tag name (the one with the string value), press enter and nothing happens. If I close the dialog box with the "X", nothing appears in the alarm text. If I add "{0} in the alarm text box first, then try and add the tag, again nothing happens. The help manual is far from helpful in describing how to use this dynamic text feature. Has anyone had success in using this feature?
