#41 Fatal error creating form element?

[Matt Ion]

Trying to create a form element, I get:
Fatal error: Call to a member function on a non-object in
F:\users\triple-c\www\mod\phpwslistings\index.php on
line 151 after hitting Save.

All components are latest available version except PHP
(4.2.3; 4.3.3 has other strange issues).

I haven't tried a lot of different form configs, I'm trying
to create a drop-down list of sequential numbers, 1-10.
