I've started an app that currently only features a screen.initialize and a SAVE button. I use a tnyDB, and everything works fine during data entry. I'm having trouble saving and retrieving data from the DB when I open the app. I'd like someone to look at the attached .aia file and correct any errors. Thanks.

For the phone users, I've made it accessible.

Screen1 blocks download, after a Clean Up:
At first glance, you have a rubble problem, and can't tell the difference between local and global variables?
Unfortunately, AI2 does not have a translate facility that can turn blocks and variable names into English, so I stalled.
From the look of your blocks, here is some remedial reading on lists and variables:

Look for the chapter on variables in the free online book.
Because you are charting by time:
I'm not good at AI, I've been around for a while. I can distinguish a local variable from a global one. I'm having some difficulty recalling data stored on tiyDB to load into a listview. I was asking for help (an example) using blocks in the viewer.
I just put the final touches on an app that stores data by time in TinyDB.
(I wrote it to keep track of my daily exercises, to make sure I did them.)

I must run the app and load its daily schedule, then actually do the exercises, before documenting it.)
