How to setup form for multiple answers for one question

Question

I want my google docs form to allow up to three days to be chosen by our users for lab reservations. I've tried allowing them to enter text, but they make errors. I have tried putting 1-31 as list items for them to choose multiple days, but it randomly generates false dates such as 7/28/2037, rather than list the 3 days chosen, occasionally. It lists the correct dates chosen most of the time. I need it to list the dates chosen always.

Answer 1

I think you need to format the spreadsheet as plain text for that column before data is submitted.
