Setting Up Color Format For A Date Field After 14 Days of Inactivity



I currently have two columns: Milestone Status and Date Updated. I set-up a workflow so when a user makes a change to a cell in the Milestone Status column, it's subsequent Date Updated cell marks the date in which the Milestone Status cell was changed.

I want to set-up a function where, if a user has not made any changes to a Milestone Status cell within 14 days of the last change, the subsequent Date Updated cell turns red until someone goes in and makes an update to the Milestone Status cell.

I tried conditional formatting, but it doesn't have the option that I need. How would I go about doing this? Please let me know if there is anything that you would like me to clarify.

    Hi @Benjamin O'Leary

    I hope you're well and safe!

    Try one of these methods. Both would require you to add a so-called helper column with one of the formulas below, and then you'd reference it in the Conditional Formatting rule.

    Column Type: Checkbox

    Details/Information: Checks the checkbox if it's 14 days or more since the last update.

    Formula: =IF([Date Updated]@row <= TODAY(-14), 1)

    Column Type: Text/Number

    Details/Information: This shows the number of days since the last update.

    Formula: =NETDAYS([Date Updated]@row, TODAY()) - 1

    Would any of those options work/help?

    I hope that helps!

    Be safe and have a fantastic weekend!

    I'm trying to do something similar using the system generated Modified On column. I'm using this formula in a Text/Number column: =NETDAYS((DATEONLY([Modified On]@row), TODAY())) - 1

    It's giving me "#UNPARSEABLE"

    Hey @JSpears

    Looks like you have a few extra parentheses that don't need to be there 🙂

    Try this:

    =NETDAYS(DATEONLY([Modified On]@row), TODAY()) - 1
