Trouble with displaying Dialog GUI

[WackyWildCard]

I'm a little frustrated and puzzled; I've been attempting to research it with little success...
I'm trying to display the dialog GUI I've made, but only the Text Display Background works.


The Game is set for SierraWithBackground

I have GUI #5 (Text Box) set  for Dialog Options.

I have GUI #5 (Text Box) set for Custom Text Box.


The Background has a parchment look to it.


Everytime I start my game, and the characters speak, only their text shows, but no background GUI displays.

Please tell me how to correct this problem.

Thank you!
