Problem with Variable Scoping in Rebol's Object

I have modified the rebodex app so that it can be called from rebol's console any time by typing rebodex. To show the title of the app, I need to store it in

app-title: system/script/header/title

so tha it could be used later in

view/new/title dex reform [self/app-title version]

That works but as you can see I have named the var name "app-title", but if I use "title" instead, the window caption would show weird stuff (vid code). Why ?

You have this

title: fld return

so title is a rebol object ... not text.
