Need Javascript Guidance for Popups

Hi All,

Let me start by saying I have very little experience using adobe and even less experience writing javascript code. I have a pdf form with many different check boxes on it, and I was asked to create a button that will allow the person filling out the form to do so via popups.

For example, there is one checkbox for a statement that says something like "2+2=4", another that says "2+2=5", and a third that says "2-2=0". I would like to create a button that opens a popup which askes the user if 2+2=4. If the user hits yes, the check box becomes checked off. If the user hits no, the check box does not get checked off. 

Regardless of the users answer, I need another popup to open after the user imputs their answer into the first (and it disappears). So after the user clicks "yes" to "does 2+2=4", the checkbox will populate, the popup will close, and another popup will open and ask "does 2+2=5" (and then answering this question will do the same thing as the previous). And so on and so forth.

I hope that example was clear enough, but essentially what I am looking for would be the Javascript syntax to execute two separate operations: 1) have input in a popup affect another form filler, 2) have input from a popup make another popup appear. I understand that there is a custom dialogue box command, I have just had some issues tying to understand and learn how to use it in this context. 

Any help would be greatly appreciated, thank you!
