Hi David,

I'm not sure what you mean.

Can you describe your process in more detail and maybe share the sheet(s) or some screenshots? That would make it easier to help.

Have a fantastic week!

Hi Andree,

Freq - The frequency of the maintenance

Date dernière Maintenance: Date of the last maintenance

Date prochaine maintenance: Date of the next maintenance

What i want to do, if date of the last maintenance is empty then today's date, if not, date of the last maintenance + Freq

Thanks!

Try this.

=IF([Date dernière Maintenance]@row = ""; TODAY(); [Date dernière Maintenance]@row + Freq@row)

The same version but with the below changes for your and others convenience.

=IF([Date dernière Maintenance]@row = "", TODAY(), [Date dernière Maintenance]@row + Freq@row)

Depending on your country you’ll need to exchange the comma to a period and the semi-colon to a comma.

Did it work?

Have a fantastic week!

Missing column in Report if I use a formula
I'm not able to "view by" a field that I have in my sheets - Quarters (Q1, Q2, Q3, Q4) - in my report. I think it is because I have used a formula to calculate the quarters in my sheets. Does anyone know a way to get a formula based field on the dropdown for view by in my report?
SUMIF function not working
=SUMIFS({GM Compliance Trained}, {GM Compliance Training Dept}, Department@row , {Compliance Training Date}, MONTH(7, 8, 9)) GM Compliance Trained is the number of employees trained.
