Whoops, totally forgot about that!

I did also discover that when recalling an earlier variable, it doesn't like capital letters. I added the responses.xls file, but it wouldn't work until I changed the variable name from <HHHmem1-happy> to <hhhmem1-happy>. This in spite of the fact that it was the same, casewise, in all three locations (original essay, where it was output, and responses.xls).

Though that might be good to know for anyone else who might have this problem.

Thanks for your help!
