[Pw_forum] problem in calculation by 4.2.1 version

[yaldaa kh]

Dear all
Beforehand, i did calculation about NO molecule in gas phase by pw.x
version 4.0 , when tried to repeat my calculation by 4.2.1 version
with the same input file, it emerged problem and stopped calculation
with this message:
-------------------------------------------------------------------------------------------------------
Bad data for namelist object starting_magnetization
namelist read: misplaced= sign
bad data   for namelist object starting_magnetization
stop 2
----------------------------------------------------------------------------------------------------------
the input file is :

 &CONTROL
 calculation  = "scf",
 title        = " ",
 prefix       = "nag1",
 pseudo_dir   = "/home/f/espresso-4.0/pseudo",
