** Using WeBWorK **

ANS(num_cmp("DNE", strings=>["DNE"]));

and get a pink screen and the warnings below when the string DNE is entered. No answer is registered as being entered in the box which previews answers and indicates correctness.

If a numeric response is given, it is accepted, marked wrong, but without a pink screen.

This format is the one listed in PGAnswermacros.pl.

Is there some other change of which I am not aware?

Thanks

Tom

Apache error logs state:

Wed Feb 22 15:52:52 2006] [warn] [client 129.170.147.62] [/webwork2/opencalc/OC02-02-Limits-Graphical/1/] Use of uninitialized value in numeric gt (>) at /var/webwork2/lib/WeBWorK/ContentGenerator/Problem.pm line 257.

Clearly the strings => ["DNE"] is getting corrupted

   my $temp_ans_hash = &$ans_eval($ans);

   my $temp_ans_hash = $ans_eval->evaluate($ans);

Hope that helps.

Thanks for any other ideas (aside from upgrading to 2.2 in the middle of a term ;-) )

Reloaded apache. Not sure why that .pl file is cached, but restarting apache resolved the issue

Thanks
