I am experiencing a persistent **"Fail - edge15 Table Format Is Correct"** error in Exercise 4.1 Here is the code:

edge15: 0!select  
edge: sum edge,  
qty: sum qty,  
numTrds: count i  
by minute: 15 xbar time.minute  
from trade  
where date = last date, time \>= "t"$09:30:00.000;

## Even though the output values match the expected results, the format test continues to fail. Could you please check if there is a specific attribute or data type requirement I am missing? minute edge qty numTrds

Hi @ghitaudiana20 ,

You don’t need to unkey your table with 0!

If you remove this, your code should pass 4.1.

Hope this helps,

Laura
