You would be better off jumping to a new context and building up your number, 
digit-by-digit as it is entered, in a channel variable.

In your "s" extension, set your variable to an empty string; do a Background() 
and then WaitExten() for a digit to be entered.  Have an extension _X to 
capture each digit and append it to the number so far.  Then use a GotoIf() to 
jump to the WaitExten() statement if insufficient digits have been entered so 
far.  You might also want a * extension to clear the number entered so far, if 
the user makes a mistake.


If you need a written example, I might be able to dig something out later.
