SQL SUM - producing wrong results

Hi

Please look at the queries here

You will see the first results which show the correct results

What I'm trying to do is group the results by days, and give an overall sum for each column
however, i'm getting all -1 results and then werid results for [23-00] column

i'll actually be selecting lots of machines (removing the MachineId=160 bit)
and selecting over a 14 day period, but removed for simplicity

what am i doing wrong

Your column-names have special characters and do not start with a letter, therefore, you must enclose them in an object-delimiter (like brackets, or double-quotes).

This: sum(06-07) as [06-07]

should be: sum([06-07]) as [06-07]

I now get

Msg 8117, Level 16, State 1, Line 4
Operand data type bit is invalid for sum operator.
