Changing default commands on wrksplf

We have customized wrksplf, but now it no longer works.

'The commands behind the option "1=Send" are stored as first level
message text in message ID's CPX3438 and CPX3439 in the QCPFMSG message
file.'

I got this from this list a while back.  We recently finally upgraded the 
release to
V5R3
and had to recreate the command.  Now, when we run the option, we get 

1) an error that 'Command xxxx in library *NLVLIBL not found.

Okay...   I tried making the library name explicit (its in QGPL) with 
?QGPL/xxxx ....

Now we get

2) an error that 'String beginning 'xxxx      ' not valid command name.

Any suggestions on what needs to be fixed here?
