Hi,

Thanks for the reply. I figured out how to do the first part of this task a little while ago. I used Direct RT. Basically, it does exactly as I want it to, to a point.

It loads the equation (call this screen #1). Then the P can press the spacebar to bring up an answer box. If they don't do that in 10 secs the answer appears on the screen (call this screen #2). They then have all the time they want to press the spacebar and answer the question.

That's fine. What i am having trouble with is the second requirement of the task. I want to be able to program it so that if they type in the incorrect answer (after bringing up the answer box on either screen) it reloads screen #1 and the process starts over again.

Basically, it is a task to see if people cheat. And if they don't wait for the answer to come up the first time, will they wait for it the second time, or third time, etc. after they enter an incorrect response. Does this make sense?
