Use of dgIndex

[Michael Doub]

Can someone explain to me where you are able to use the dgLine and dgIndex properties?   In the script below I am falling into the condition where no value is being returned for dgIndex.   Do I have a syntax problem?

Thanks
   Mike

   put the dgControl of me into theGrid
   put the dgIndex of theGrid into tinder  
  
end FillInData
