Var Out for multiple variables

Hi,


I have two variables from an embedded experiment that I wish to display on the last page of the questionnaire. They are correct response times for 'Go' tasks and number of correct responses. I think I have two problems. The first if that my average response time isn't calculating at all. My second is that only the Var Out variable mentioned second under options is carried to the questionnaire.

I have 2 questions
1. Is there anyway to carry two variables over?
2. Can anyone spot where my average response time for correct answers, excluding those which correctly timed out, is going wrong?

Thanks
Kerstin

set &MyRT mean c8; select c9 != 1 ; select c7 == 1 #c8 are response times, c9 errors are = 1, and c7 correct (not timeout) ==1
set &MyCorrect count c9; select c9 != 1

text 0 -150 "THANK YOU"

text 0 0 "Scores shown at the end of the survey"

text 0 100 "Please click space to continue."

end

I've tried 

options
var out &MyRT
var out &MyCorrect

but only the &MyCorrect appears at the summary page feedback
