>I've used the example from help on how to generate random numbers. Now I need a random number between -1 and 1 (integer -1,0,1) and cannot figure out how to modify the example to give negative and positive numbers. Any tips?

You are not showing any example of what you are trying to do. There is only one integer between -1 and 1 though and that is the zero. What does the example code look like?
