They work 20 shifts a month.

They complete 4 sales on 01/12/2011 and 3 sales on 02/12/2011. 

Total of their 2 shifts was 7 sales

I want to work out how to show them what is the forecast monthly result.

I could do this using a formula in google sheet.

Can some one help with how to help on this one in zoho reports. 

Btw: it is for a table 14 salespeople.

Thanks
Reuben
