from the help pages for error# 4391:

For example: If you say "put-long(x, 5) = u" where u is unknown, you will get this error. To ignore the error, use NO-ERROR.

perhaps if you shared the code that caused this error or tell us what you are trying to do, we could help better.

I think "share the code" was the more important part of the suggestion...
