#1 Fatal error: Call to a member function o

[Tim Kolecke]

I think I've got everything set up right. Everything is
working except for the graphs. I'm getting Fatal error:
Call to a member function on a non-object
in /path/to/html/lal_web/lalexecute.php on line 231 when
trying to do run a predefined graph. Any ideas?
