[Pw_forum] from read_namelists : error # 17

[robinshy]

Dear PWscf professionals，
     I use this software sometimes and feel it is a very powerful tool for structural relaxation on many cases. But 
recently , when I use it as usual to do a vc-relax, an accident mistake came out. I check 'system' part again and again but it 
seems that there is an obstinate error here. I'm not sure whether it caused by the crystal information presenting wrongly or other
reason. Can anyone give me a help! I'm so appreciate it!
error like this:
