[imapfilter-devel] function question

[John Webster]

I'm trying to define the following function:

badCharsets = function (mailbox)
     local result1 = mailbox:contain_field('Content-Type', 'koi8-r') +
               mailbox:contain_field('Content-Type', 'iso-8859-9') +
               mailbox:contain_field('Content-Type', 'windows-1254') +
               mailbox:contain_field('Content-Type', '-=SPLIT') +
               mailbox:contain_subject('=%?utf-8%?Q%?') +
               mailbox:contain_subject('=%?iso-8859-9%?') +
               mailbox:contain_from('=%?iso-8859-9%?')
     local result2 = mailbox:is_undeleted()
     return result1 * result2
     end
     

However I'm getting the following error:

   attempt to index local 'mailbox' (a nil value)


Can someone tell me why?

Thanks.
