The easiest way to do this is to make each of your input layouts separate
pages.  Then you'd have a button on the first page with a script that
executes "GoTo Page 2" and sets a variable so "myVar:="Choice 1".  On page
2 of your layout you have a nonenterable variable (myVar) which will
display the value you've set.  You'd have another button for your third
page.  myVar can be used elsewhere as a flag if need be.

In this case, you'd use the myVar flag to set the page number of the input
layout when you go to it.  The way I do this is to use an invisible button
on the layout with a script (and the "only if modified" checkbox turned
off) to run my Before phase stuff.  Since myVar has been previously set,
I'd do something like this:

	If(Before)
		Case of
		:(myVar=1)
		GoTo Page(2)
		:(myVar=2)
		GoTo Page(3)
		End case
	End if

This is the barest bones summary of what you need to do; other
enhancements would include buttons on each of your pages to reset your
Choice variable on the fly.

Hope this helps!
