change condition to:
"$!request.cntryCode" != "" && "$!request.cntryCode" != "es"
if it's not empty string or non present or not es ($! in front of the
var means if it's null nothing will be displayed. See info here

Wait, if I understand well this code, this means: if request country
code is _not_ cr, then include Sandbox.Trycr. Concatenation sounds good,
but with what? because concatenating the request param at the end of the
doc name would mean if the country code is cr, include Trycr.
In any case, for concatenation this should work:
{{include document="Sandbox.Try$!{request.cntryCode}" /}}
, using formal notation to prevent velocity interpreter from getting
confused by surrounding text (see info here about formal notation

).
Have fun,
