But, when I try use tinyDB, I've got an error.

Keep the first two blocks underneath 'when Button1 click' and add the 'TinyDB value to store' block and make the value a text string with 'hasil' in it. Then, change the value to store to 'get global hasil' and change the last block to not have the 'start Value' and only open another screen. On the ResultScreen, initialize global hasil to 'TinyDB get value' block and make the value, 'hasil'. Next, change the ifValueNotThere to '0'. Drag the block to where the 'get start value' block is and delete the 'get start value' block. Hope this helps! Screenshot 2021-04-12 2.39.39 PM

Use different screens wisely

If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...
