Multifield Dialog not working correctly - Dynamic Stamp

Hello All!

I’ve developed a dynamic stamp in Acrobat that successfully generates a unique ID, prompts the user to "check boxes" aka. Textfields that are populated with an X if the respective value is input, and collects text input for fields, each via separate dialogs or prompts. However, I’m struggling to combine the text field prompts into a single multi-field dialog for a smoother user experience.

First I wanted to work out only the text fields and when that works, the goal would be to also have thge "checkboxes" in the same dialog (not a must)

Has anyone managed to implement this, or can offer advice?

What works:

1. Calculate an unique ID-number for each stamp.  A trusted function handles incrementing and saving a counter. The stamp script then reads this value each time the stamp is applied. (✓) 

2. Prompt user for checking boxes. A dialog prompts the user to choose "a" or "b", and the script marks the matching checkbox aka textfield with an "X".  (✓) 

3. Prompt user individually for each field with app.response (✓) 

--------------------------

Now this kindoff works. But it only inputs the last value "reference" and the other fields stay undefined. I'm assuming that my script saves only one value and overrides the others? Where is the mistake?

if (event.source && event.source.forReal && event.source.stampName == "#SampleStamp") {
var formData = {};

var formDialog = {
initialize: function(dialog) {},
validate: function(dialog) {
var store = dialog.store();
return (store["category"] !== "" && store["type"] !== "" && store["title"] !== "" && store["reference"] !== "");
},
commit: function(dialog) {
console.println("Dialog store: " + JSON.stringify(dialog.store()));
var store = dialog.store();
formData.category = store["category"];
formData.type = store["type"];
formData.title = store["title"];
formData.reference = store["reference"];
},
