The menu looks weird, and there are two error messages:
- The string "01" isn't the same type of data as the number 0
- You might want to convert one side to a number using (num:), or to a string using (str:).
- You can't get any data values, let alone the string "length", from the number 0
- I tried to access a value in a string/array/datamap, but I couldn't find it.
