[CP2K:3905] Problem with singlet and triplet state calculation with CP2K

[bharat]

Dear Zamaan,

Thank you very much...

The calculation runs good, however I did not get the consistent results but 
I found the differences in the results.

do you have any Idea why i did not get the Net charge ZERO? My system is 
ZnO. I have calculated using gaussian, I found that total charge is zero.
I got the WARNING MESSAGE TOO...
