Adding and Removing Elements (Using Tickers)

I am having a hard time adding another object with tickers. I am trying to get eqn2 (i.e. 3+2=some input) to move down with the response() function. You can see in the response() function that the alert "New Question" is being called onto the screen correctly. The goal here is to have m=2 (it was at 1 before) so that the drop(2) gets called moving eqn2 down. I think the issue is that the ticker doesn't go back far enough to recognize obj[m].x = Math.random()*can.width that obj[m].y = 0.5. I don't know how to get it to work here, and any help would be much appreciated.

Solution

This isn't really a ticker question. You have to redefine the variables you need in the response function before the ticker.
