|Mark Schmitt - Previewer Errors with Complex Answers
4/1/2002; 2:32:42 AM (reads: 638, responses: 0)
have run into a strange error. When I have a problem that requires a
complex number for an answer (for example, find the sqrt(-4-2i) ), and
I type in the correct answer (.4858682718-2.058171027i), and preview
it, I get the pink screen with the following error:|
Compiler warnings: * Use of uninitialized value in concatenation (.) at /home/httpd/webwork/system/courseScripts/displayMacros.pl line 211. ##More details: -------- main::preview_answers called at /home/httpd/webwork/system/cgi/cgi-scripts/processProblem8.pl line 526
The previewer deletes the answer I typed in as well. (Only from the ans_rule box. It appears in the parsed box and in the preview box.)
If I submit the answer without previewing, everything works fine. It's only when I try to preview that bad things happen.
I'm wondering if PGcomplexmacros might have a hidden incompatability with the previewer.
Any help would be greatly appreciated.
