I would think that by now, you would have enough experience to tackle these
sorts of problems yourself. There are examples in the test/antechamber area
of molecules containing chlorine (e.g. sustiva). You can explore how what you
are doing differs from the examples that work. (My wild guess is that you are
confusing atom name and atom type, or that you didn't load gaff.dat into
LEaP.)
In any event, just citing the error message above, with no details about what
you did, doesn't give anyone on the list a chance to help.

I'm confused here as well: why not just try the experiment and find out for
yourself?
