How to read cell from the excel sheet after Value(09) using this . DDT.CurrentDriver.Value(09)

I am unable to read columns from the excel sheet for data seeding after 9th column. My script is failing where it is highlighted in red. Any suggestions on how can I read next column.

page.fieldsetDriverRestrictionUmpf274.textboxNafb41birthdateyyyy.Keys(DDT.CurrentDriver.Value(09));
page.fieldsetDriverRestrictionUmpf274.textboxDriverSlicense.Keys(DDT.CurrentDriver.Value(0(10));
