Linking datas on separate sheets

Hello,

I've been asked to do an event reservation scheduler and an income report in one file.
The case is, if you entered the date and an activity on the "JAN2014" sheet the activity description will automatically be copied on the "January" sheet on the specific date and venue entered. Same goes with the other months.

Here is the draft sample file.

I really need help THANKS!
