E-prime didn't record all my reponses from my button box

Hi,
I bought a button box from Current Designs. For my study, each trial has more than one response answers, for example, for first 10 second trial, the subject had to type 12344321 on the button box, but my E-prime only recorded the first digit "1" as a result. How to make E-prime to record all the digits the subject have typed? Thank you
