That's not right marshal. The rule says the two words must be inside.

Thus you could have said:

UNILATERAL

Which would comply with the rule by giving "NIL" and "ERA"

I'm shocked that such an excellent poster as your goodself, has made such a slip, please get a grip!

[marshallhouse]

Woops, sorry.  I'll have to pass on that one then.  My brain's gone numb at the moment.
