Hi all.

I have a form that allows end users to edit fields and place the original data in a historical table. The issue I'm having with the below code is that if the original data (txtVendorItemNumber_Original) is blank it will not insert the new data (txtVendorItemNumber) into the table. It works find with the original data does not match the new data in the form, but when the original data is blank then it will not update the new data. How can I get it to work when the original data is blank?

If (Me.txtVendorItemNumber_Original.Value <> Me.txtVendorItemNumber.Value) Then
    
    CurrentDb.Execute "insert into ProductSpecificationsEdit(ItemNumber,ProductSpecification,OriginalValue,UserID,ChangeDate) values ('" & Me.txtItemNumber & "','" & "VendorItemNumber" & "' ,'" & Me.txtVendorItemNumber_Original & "', '" & GetUserName() & "', '" & Now() & "')"
    CurrentDb.Execute "Update  ProductSpecifications set VendorItemNumber = '" & Me.txtVendorItemNumber & "' Where ItemNumber = '" & Me.txtItemNumber & "'"
    change_count = change_count + 1

End If

How about this?

If (Me.txtVendorItemNumber_Original.Value <> Me.txtVendorItemNumber.Value) Then
    If Not IsNull(Me.txtVendorItemNumber_Original.Value) Then
         CurrentDb.Execute "insert into ProductSpecificationsEdit(ItemNumber,ProductSpecification,OriginalValue,UserID,ChangeDate) values ('" & Me.txtItemNumber & "','" & "VendorItemNumber" & "' ,'" & Me.txtVendorItemNumber_Original & "', '" & GetUserName() & "', '" & Now() & "')"
         CurrentDb.Execute "Update  ProductSpecifications set VendorItemNumber = '" & Me.txtVendorItemNumber & "' Where ItemNumber = '" & Me.txtItemNumber & "'"
         change_count = change_count + 1
    End If
End If
