Aggr syntax check

[samuel_brierley]

Can someone spot where im going wrong?

aggr(avg(count({$< MainCarriagewayDataFilteringOutput.site1.v = {'<50'}>} Timestamp)),weekday(Date))

what its supposed to do is produce the average number of minutes (theres one record a min) for each day.

The 'dimensions' in an Aggr() cannot be calculated dimensions, only field names are allowed here.

Learned something new today . Thank you jonathan
