 Dear Phil,
When the Save button in the remote form is clicked on, the below method will call the table class "taDepartments" method to check for duplicates before updating records:

On evClick

Do method $validateZeroValues

If iNewRecord

Do iDepartmentList.$DuplicateNew(iDepartCode,iDepartDesc) Returns lvFlag


If iDepartmentDescription<>iDepartmentDescriptionOld

Do iDepartmentList.$DuplicateEditDescription(iDepartmentDescriptionOld,iDepartmentDescriptionNew) Returns lvFlag

If not(lvFlag)

Quit method 

End If

End If

 Hi Martin,

For the avoidance of doubt, presumably you are executing this statement 
somewhere, and then fetching the results?

Some lines like this:
Do toSession.$newstatement('PG') Returns lsStatement
Do lsStatement.$execdirect(pcSQL) Returns lnResult
Do lsStatement.$fetch(pcResults,pcResults.$linemax)
