## How to use Duration.Days with Nulls in Date Field

Using the following function returns nulls where the [Start_Date_c] field has nulls. How do I get it to return 0's instead of nulls?

``= Table.AddColumn(#"Removed Columns", "Tenure(d)", each Duration.Days(Date.From(DateTime.LocalNow())-Date.From([Start_Date__c])))``

I was able to solve the problem by first checking if the Start_Date_c column was null and if so, using Number.FromText to assign a 0 else finish the calculation of Duration.Days().

``= Table.AddColumn(#"Removed Columns", "Tenure(d)", each if [Start_Date__c]=null then Number.FromText("0") else Duration.Days(Date.From(DateTime.LocalNow())-Date.From([Start_Date__c])))``
