Hi all, i'm trying to offer students in a course a way to indicate what times each day they are free and what times they are occupied. I envision a table with days of the week across the top and times of day (9 am, 10 am, 11 am, etc.) down the side. Students would simply put an X in a box (a checkbox) to indicate that they are busy at that time. For instance, someone who is busy at 3 pm on Tuesday would put an X in the place on the chart where the Tuesday column and the 3 pm row meet. I can't figure out what activity to choose to set this up, though. Database? Dataform? Questionnaire? Any suggestions on how to pull this off? Thanks.
