indesign formular

Hello people,

I have wrote a function that creates a window

I can also write anything in the window

Could someone help me to add 2 more textfields in the formular

so the user can write in 3 different fields?

function Myfunction(){
var myInput1=prompt("Write a number","","My new prompt");
if(myInput1==null){    exit();
}




if (myInput1){
}else{
    alert("Du valde inte att skriva något jobbnummer");
}
}



}

I am not sure if prompt support this kind of method.

Thank you in advance.
