When I read Conrad's suggestion concering my Hypercard find problems, I 
thought he had the answer--my fields were numbered such that the first 
search (find the right HEADING) took me to a field with a higher number
than that for the second field (find the right Subheading,) and so 
HyperCard went to the next card before it began its search.  

I quickly gave his suggestion a try.  I was sad to find that I had my 
fields numbered in the order that _should_ work.  

I tried the two searches manually, and they worked properly.  In the 
script, though, they don't work.  I don't think I'm doing anything 
between the two find commands that should disturb the process...
Here are a few lines from the script:

    repeat [until you find a subject line]
        ...
        if (char 1 of theSubject <> space) then
->        find theSubject in bg fld Subject
          exit repeat
        else
          (look a line earlier for the SUBJECT line)
        end if...
    end repeat
    
    --   First, we get the contents of the line, from after the last space
    --   to the first period of the leader;

    put offset (".",theTopicLineText) into length
    put char 3 to (length-1) of theTopicLineText into theTopic
    
    --   then we find the first card with it in the topic field.
    
->  find theTopic in bg fld Topic

I can get it to work by throwing in a "go previous card/go next card" pair,
but that clutters up the recent card list.  

What gives?
