Where is the acrobat popup control button?

I am new to using the Acrobat 5.0 and I have been trying to use it for days. I have read at a website that to display the acrobat popup control button, you have to run the code on the Java Script console (i.e. var cRtn = app.popUpMenu("Apples","Oranges","-","Beans","Corn")). I have been trying this but nothing is happening. Might I be doing something wrong? Please help, I am looking forward to your answers. J
