That macro will have a problem with PG 2.20. The JSON module is no longer used by webwork or PG. Instead the Mojo::JSON module is used. So the parserLewisStructureTool.pl macro will need to have line 281 deleted. That is the line that reads my $json = JSON->new->allow_nonref;.  Then the lines that call $json->decode need to be changed to call Mojo:JSON::decode_json instead.

Thanks so much Glenn! This worked. I really appreciate it. 

I used a double colon after Mojo for anyone reading but followed these directions otherwise exactly.

Yes, that should have been Mojo::JSON::decode_json. That was a mistake.
