Using multiselect value in a mySQL query

Hi everyone,

I don't know how to proceed and need some help. Once I click on a button, I run a script that is basically working through all the necessary elements to get the values and save them into my mySQL database.

The question is a simple text that will be saved. The same goes for the answer.
Only categories is a multiselect, which I get as an array and I'm not sure how to implement it in retool, so that I can save the chosen categories with a query in my database.

That's how my script looks like.

// (1) save question

// (2) get last insert id from MySQL
var question_id = get_last_insert_id.trigger();

// (3) save question and category
// for each category we need to save one row
var categories = neue_frage_kategorien.value;
let question = get_last_insert_id.trigger();

categories.forEach( function(category) {
    additionalScope: {
      questionId: question_id,
      categoryId: category

// (4) save answer
save_answer.trigger(neue_frage_antwort.value, question_id);

I get a message error, saying the following:

Error:`trigger` options must be an object neue_frage_speichern
in run script(neue_frage_speichern)
in neue_frage_speichern click event handler(neue_frage_speichern)
from user interaction

And I'm not sure what I'm doing wrong.

Hey Pascal!
Welcome to the forum :).
You can't just put your own objects into the trigger function :-). You should move them to the additionalScope or similar in your 4th part, as in your 3rd part of your script.

Hey Jonathan,

aaah, oh! Now I see the problem and that makes sense. I will give it a try. Thank you!
