Hello everyone!
I have a question regarding programming an app in thunkable: I am currently working on a project in school (I am in 8th class in Germany) and try to create an app that counts your daily waste / garbage and helps to reduce it. I have a problem and can’t find out by myself - here it is: I would like to use a calendar (I already got a template for this) but can’t find out how to implement a data at one specific date and how to store it… It’s a bit the same idea as adding your own weight at a specific date and store it. It would be great to get a graph out of it also, that shows the different days with the given data.
What I have so far is a stored variable - the app gives you a list of things to choose and you can add the value. But how to connect this with a calendar…? Thanks in advance - I really appreciate your help.
Stay safe!
Mia Jasper

Hi Mia, welcome to Thunkable!
Can you either share the template project link or offer a reference to it? It’s hard to know how to help you without knowing how the calendar feature is set up.

Hi tatiang,
thanks for your welcome and thank you for your answer.
I built a prototype with that specific function:
[Prototype](https://x.thunkable.com/projects/5fc77e15d09a8800113da8df/041cfd68-38fa-4f66-91f7-f14ad3b0bc79/designer)
Today I got the hint that it might be better to use the “date input” function instead of the calendar function (thanks to rollke).
My question is: How to store the data for each single day (at the moment the app just adds every input) and how to connect this with the “data input”. At the end I would like to have a graph that shows a cummulation of each single day.
Thank you very much for having a look into it.
Sorry that I can’t explain it better - let me know if you have any questions…
Thanks!

Hi,
you could use Local\_DB (a sort of spreadsheet with rows and columns) or you could try lists of lists.
The best way would be to use Realtime\_DB. But for that your users have to use a Firebase (internet connection) and you have to provide a Firebase account. I think that is a “bit too much” for a school project.

Here is a small example for a solution with lists of lists.
The list for kichengarbage (as a stored variable) is a list containing small lists with two elements (type of garbage and counter for that type).
In the textfield you enter a type of garbage. If it is new, the new element will be appended to the garbage-list. If this type is already in list (else) the counter will be increased by 1.
