MPI Blank Dialog Bug

[Gnuoy]

edit: problem was variables weren't being set

These triggers were set up in a really poor way without arrays but I'm to lazy to fix that now. There's a bug where it just shows players a blank dialog box sometimes and i'm not sure why, assuming it's not a typo. I'm posting two of the triggers below but these are repeated across all the players, if that makes sense. I suspect the bug is when two players try to join the same king at the same time, but I would think that should just clear all the dialogs anyway, again assuming it's not a typo, which is highly likely since these were set up in such a poor way. If anyone can point out anything that might cause a blank dialog to pop up, that would help. Thank you.

Goal: stop the blank dialog boxes from popping up.

I think it would be useful to see the trigger that creates the dialog itself, perhaps there's something wrong there

Also IIRC the usual way to handle dialogs is like so

• Actions
  • Dialog - Clear MyDialog
  • Dialog - Change the title of MyDialog to The Title
  • Dialog - Create a dialog button for MyDialog labelled Button 1
  • Dialog - Create a dialog button for MyDialog labelled Button 2
  • Dialog - Create a dialog button for MyDialog labelled Button 3
  • Dialog - Show MyDialog for Player 1 (Red)

Note the "clear" action before anything else, it's a bit weird, but I recall having empty dialogs fixed that way
