Hello,
I think, you have to alter ur structure little bit. Go to your data type and change the order of "FileName_Values" node, so create it just after oildex_File node and then test ur file output?
BTW, if i am not wrong at least twice i have told u that don't merge multiple questions in a single thread. So, in case you have other questions then please raise a new thread.
Thanks
