I've been sifting through your posts and have enjoyed seeing where some of the current materials on the wiki pages have started - great job Eric. And I appreciate all the explanations that have been offered on the wiki page, including limitations, when uploading XLS forms to CCHQ.
I recently posted a question that has failed to garner enough attention or replies, but I'm wondering if you have gone through similar issues before - I've been testing Xform uploads onto CCHQ and have been noticing that all select_one and select_multiple automatically convert to multiple choice and checkbox lookup tables. I'm not sure why this happens and what's a way to work around that. If you have faced this issue and can let me know how you deal with it, I would very much appreciate it.
