Without the expression you were evaluating it's hard to tell, but I 
suspect you evaluated an expression you expected to have a numeric 
value and it does not.  You can use TraceDialog[expression,Message
[___]] to enter a dialog at the point in evaluation that the message 
is issued.  The offending expression should be the previous 
expression on the Stack.
