Hi Ammon--
From your example, it's not clear what you need but...
View requires a face object or the result of a layout
block. You need to defer calling View until you can
supply those args.
Ask is reserved for collecting user input from the
console window. If you want to gather input from the
console and *then* use View to produce an interface,
try something like (assuming lyts is defined):
result: ask reform ["Which layout; " lyts "?"]
lay: layout [
h2 gold "You selected:"
content: text black 200 ""
]
content/text: result
show content
view lay
If the View engine is already engaged, request-text is
the preferred method. Try (again, assuming lyts is
defined):
lay: layout [
h2 gold "Select a layout"
content: text black 200 "Click Ask to continue."
button "Ask" [
answer: request-text/title reform [
"Which layout " lyts "?"
]
clear content/text
content/text: answer
show content
]
]
view lay
The Text Fields How-To doc
(http://www.rebol.com/how-to/fields.html#sect3.2.)
gives some examples of this.
