I think that blocks in procedure section is causing the error

First fix all the red errors
Then check, where exactly you are using the - operation and validate your data before trying to subtract values

i know, but its same, i got error.

Check your tinydb… It seems values are not stored properly. Drag one tingdb get items, click on do it and make sure

In which screen do you get the error? Search for the - math block there and post a screenshot of these relevant blocks
