a function definition not allowed before "{ "

i try data 2 temp.sensors data logger.
to do, took running sketch of 2 sensors ond copied data part , modified in several parts.

i checked several times , experiented several "{ "and "} " ,s kept error message coming up.
could me pls.


as shows, newby ,  surprices me datafile "opend" time.
"file datafile = sd.open("datalog.txt", file_write);" within loop , not setup part.
is usual ?
