If that's cut n' pasted, you're setting @se to be one long string of comma seperated SEs, when you probably meant to do ...

@se = ('AltaVista', 'Excite', 'Infoseek', 'Lycos');
# or @se = qw(AltaVista Excite Infoseek Lycos);
[download]

After which, the double-quoting (or better yet, no quoting: new WWW::Search($se)) method should work.
