Hi @jervischionh,

For exercise 1.3 can you make sure that if you are selecting a column from a table that you use backticks (Tables in kdb+ | Language | kdb+ and q documentation - kdb+ and q documentation (kx.com). E.g. When selecting time and endTime from the window table, instead of this:

window: (t[time];t[endTime]);

We would write it as this:

window: t `time`endTime;

This goes for the rest of the columns in your code.

For exercise 2.3 can you create a dictionary mapping the mysensor options as seen in the table below.

If you have any questions, please feel free to reach out.

Many thanks,

Megan
