it's so simple you're going to kick yourself.

a modal dialog behaves identically to a confirm, with the exception that the
returned value can be more than just a boolean.  so, how do you get the
value of a confirm for later use?  simple, you assign the call to a variable
and after the confirm has been interacted with by the user, the variable
contains the return value from that confirm.  the very same is true for the
modal dialog.
