Solved Query date or is null not working

[Number11]

So i am trying to bring back in a query the results of all call made after another date field or is null, but its only bring back null records, even though we do have calls with dates i am using

"Contact_Date"
>=[Start_Date] Or is null

 

[Minty]

The full syntax in a SQL statement would be

[Contact_Date] >=[Start_Date] Or [Contact_Date] Is Null

 

[Number11]

Thank you that did the job
