This mask is likely not what you want. Assuming that O2 etc are atom
names and 6-15 are residue numbers, you want:
:6-15,36-46.O2,O4,H3
See 28.2.2. Atom Mask Selection Syntax in the cpptraj section of the
Amber 17 manual for details on mask selection. It can be helpful to
use the 'select' or 'atom' commands to test if the mask expression you
are using is behaving as intended. Also, setting the debug level to 1
(via debug 1) prior to the hbond command will print lists of donor and
acceptor sites, which may be useful as a debugging tool.

Note that a period is not a valid operator for Amber mask syntax.
Please refer to the manual for details.
Hope this helps,
