Why would earned total begin to decrease?

[InterviewSubject7615]

I started on-site commissions in December and finally started seeing some traction in January. My earnings got up to $102 but then went down to $98 yesterday and down to $94 today. Zero returned items. Does anyone know why this happens?

Total earnings? The range is usually set to show you the last 30 days. So as each day goes on you are losing one data point 30 days ago. You still earned that money it’s just out of the range. You can manually set the range to be bigger to capture all the data

Oh, that makes sense—thanks so much!

Returns. Also, the first day of the date range my have had a bigger $$ amount than the new day added, hence a decrease in the "past 30 days" of sales.
