I am trying to get two checkboxes on my app to work like in the pictures This is my code right now:

function Checkboxes() {
if (getChecked("SoundCheck") && getChecked("PhoneticCheck")) {
setText("FirstBox", "Please select one box");
} else if ((getChecked("SoundCheck"))) {
setText("FirstBox", "Press GO! to learn what animals sound like");
} else if ((getChecked("PhoneticCheck"))) {
setText("FirstBox", "Press GO! to learn how to pronounce animal names");
}
}

FirstBox is the name of the textbook the descriptions are supposed to show up in
SoundCheck and PhoneticCheck are the names for the checkboxes

I am trying to get the If-Then statements to loop however I am unsure as to whether to use a for loop or a while loop as those are the only options I have to use and what to write in the code for the loop. I can clarify my question further if my explanation was not good. Help!
