Feedback on RT block

[MP]

Dear Eprime Experts,

I am wirting a script for a experiment. After every block of trials I want to provide feedback on RT (mean value) by block. How could I do it? How can I correctly use the FeedbackDisplay Macro @RT.MEAN? I did try to use it and I got feedback of the last trial.
I did also try to use the function Summation.Mean from the E-Basic help, but I got the same: RT of the last trial.
Any ideas about how I might do this?

Thank you in advance,
Mauricio
