Duplicate entries

Is there a way to highlight duplicate entries (serial numbers) either as an alert or highlighting a field on the smartsheet?

    Hi @Jo Pearson

    I hope you're well and safe!

    Try something like this in a Checkbox or Flag type column. (you can also reference it in a Workflow or for Conditional Formatting.

    =IF(ColumnName@row <> "", IF(COUNTIF(ColumnName:ColumnName, ColumnName@row) > 1, 1))

    Did that work/help?

    I hope that helps!

    Be safe, and have a fantastic week!

    I haven't had a chance to try the formula yet as it's got very busy, but I'll let you know how I get on.

    Kindest regards
