Dictionary structure

[Raffaele_Gold]

Hi, I love dictionary but probably I don’t know some rule. I’m going mad

With my app I want to save product by barcode and name and save the price by date
This is my block I used to save product when it doesn’t exist

This is my block when product exists and I want to add a new price in a new day or in the same day ) I created it , like update.

I see the guide about dictionay and (if I understood well) if the last key in the path exist it updates the value, if the last key in the path doesn’t exit it will create a new one . This works only for the last key, it’s right?
Well if I test the code in the day of the first add (when it doesn’t exist) and try to add a new one (changed the time with the add day block) it works fine . I tested yesterday, you can see in the db 2 items under PREZZI , 14 and 15, with their values.
I update my apk ,saved items, yesterday I added a product and a price and today when I tried to add a new price got error : Expected a list or dictionary, but found a null when walking path.
I made some test and I can find the keys , it can’t walking year and month and day . Why if I can see it in my db?

It can’t see day,month and year, if I get off them the walking is right and show also the data 2023 marzo and the 2 items

Which is my error?
Thanks

Edit I tested also before with 2 item and it doesn’t work , no update (15 is just in dB) and also with one item, new price (with only 14 in dB)
Yesterday all work fine , add , update and also new product using add day block of the clock

Some hint? There is some error in the way ai stored the data ?

[Raffaele_Gold]

What can I try to fix this problem ?

[Raffaele_Gold]

Really , I don’t know how to go on
Here the aia test, please don’t focus on other things but only the date path and why I can’t get (but I see) the date items , this is a part of all my code. How I have to change the save path ? Which is my error?
Thank you

@Still-learning usually I don’t like to tag but I don’t known how to go on ,thanks

I tried also with a variable but nothing

yes, me too noted… It accepts 2023 as a sting but doesnot accespts through clock

EDIT:

I have solved just by using trim function also changed your set textbox clear too

i have used procedure blocks to reduce the blocks usage

i hope your problem have been resolved… right? @Raffaele_Gold

[Raffaele_Gold]

I will see tonight ,thanks for now​ so is a problem of space added somewhere?

[Raffaele_Gold]

Really I don’t know why . To work right I have to use trim in get value and in store blocks or without trim as original code. With trim only in get value it doesn’t work .

Thanks for your code, I like to learn how power users work, I mean professional people and not amateur like me. This is only an aia test but your code is always more elegant than my main code
thank you

Do you believe me when I say I’m going crazy ?

[Raffaele_Gold]

I change my code with the trim block and I will test the app for days. After I will update you about the solution

[Still-learning (1-2-3-4...)]

While you save the value in dictionary, there is no need of trim… you must use only at the time of reading from path

Ok, but as you can see in the video, yesterday night with trim only in get path give me not found , worked only with trim in both position . The video is about your aia without changes and after I tried to add the trim block in store block too . But is a no sense way as you suggested me
