Can I display text from a string realtime

Here is my scenario. We have a program that will involve a slideshow in an interactive theater. Each seat in the theater has 3 buttons wired to it. Right now, visitors use these buttons to vote on which video they want to watch. We want to use the theater in some of our guided discussions. The idea is to discuss topics then ask the participants questions. They can answer the questions by pressing the buttons; agree, don't know, disagree. We want their input to be anonymous. Our AMX system will take care of tabulating the results. What I'd like to do is have a slide show where I can have a zone showing the question and a zone where I can feed the tabulated results via serial string from the AMX. Question plays, pause, then tabulated numbers displayed below. AMX will run the show but can the HD410 units display text on screen real time via receiving a serial command? I also have an HD210 and a few HD2000s laying around. Does this sound do-able?

  Is this text being displayed over an image or video, or in its own space? How would it be formatted? Yes, it's possible to do with some custom scripting to take the received text and display them in the appropriate place.

  That's great.  
  Regarding text placement, what ever is simpler will be fine. It might make the most sense to have the text display in a zone below the video (jpg in this case)  I see having a question slide, then an answer slide with the words Agree, Disagree, and Don't Know added to the bottom of the image,  Left, center, and right.  I would need the text string (numbers) to be displayed accordingly.  Left, center, and right in the zone below.  I can adjust the slide to match actual formatting coming from the Brightsign.  Or are you referring to what the string would look like coming from the AMX?  
  
  Thanks

  Ok, I have a custom autorun I did for brightauthor 2.2. It might be for an earlier 2.2, possibly not for build 39, but you can try it.
  
  Custom Autorun
  
  Commands suppported:
  Show
  Hide
  SET
  
  SHow and hide show and hide the text zone.
  
  SET:mystring
  
  Adds "mystring" to the text field.
  
  This autorun assumes you're going to add a text zone to your project and call it "TEXT_1". You can name the text zone under the edit, layout tab in brightauthor.

  Took longer than we thought to implement for a variety of reasons but your script works beautifully.  Exactly what we wanted.
  
  One of our theater techs called your purple boxes "magic".
