Hello,
Sum() is a polymorphic function it accepts both CONSTANT (scalar) and VARIABLE
(array) period, while StDev()
accepts only CONSTANT (scalar) period.
You are getting error because you attempt to feed StDev with array when it
accepts constant.
The error message tells exactly that.
Best regards,
