USAGE
ELT(position, expr[, expr] ...)

DETAILS
ELT() is a string function that returns the string that corresponds to the given numeric position in a list of strings.
The first argument is the 1-relative index for the desired string.
A non-string expr argument is converted to a string, if possible.
It is valid to specify a NULL for an expr argument as long as you want that index position to return NULL.
A NULL is returned if the first argument is NULL, less than 1, or greater than the number of expr arguments provided.
