feedback object - correct answer one of many

[c.frosch@reading.ac.uk]

Hi Matt,
Thank you! I knew there had to be a way to do this.

I'm not entirely sure about where I create this array. I'm still quite
new to using e-prime. Is it something I can look up in the user guide?

Thank you for your help!
Caren
