Easy question for all you ActionScript wizzkids!

Question

I have created the following Actionscript to control a 'Next
Question' button. The idea is that it will choose a random frame to
link to in the current scene (Part2).
nextQ_btn.onRelease = function (){
gotoAndStop("Part2", n);
n = Math.random()*1+3;
At the moment, when I click the 'Next Question' button,
nothing happens. What's up with my script? My programming knowledge
is very limited and this is just about all that it can manage!
The button works when I take out the n variable and put in a
frame number manually.

monkee,
There appear to be two issues with your code:
1. you're calling n before you have defined it
2. you need to generate a random whole number and the random
number generator will have decimals
The solution is
1. call for n after you define it
2. use a rounding action to make the random number a whole
number
So:
nextQ_btn.onRelease = function (){
// generate a rounded random number between 0 and 4
n = Math.round(Math.random() * 4);
trace (n)
// go to the random number +1, making the range 1-5
gotoAndStop(n+1);
As you may already know, the trace action helps solve these
types of issues by letting you know the value of n if it is
defined... when you test movie, the results of the trace statement
show n has a value in the output window. In your original code, it
would show undefined.
Hope this helps. One other thing you may face is figuring out
a way not to ask the same question twice. You probably will want to
use an array of eligible questions before long.
