Modify the lines in your program like this:

numberp AND (1 > :v) (:v > 13) iftrue [messagebox [error] [your first 2
inputs must be numbers between 1 and 13]]
iftrue AND (:t AND (2>:x) (:x>3)) [[messagebox [error [you must input 2 or
3
alphanumaric digits]] stop]
assuming :t is a "boolean" true/false.

Or at least something like it. The 2nd like you still had a "range" that
Logo doesn't understand. Both numberp and iftrue test one expression for
true, and you need the AND predicate to put the tests together.
