Feeding Dropdown List Results Into Different Spreadsheet

I have to create a series of drop down lists with choices on it for people at the company to fill out to see how much time they spent on each type of project. The plan is to have people fill out a "daily form" to see how much work they did that day, and have the results of that feed into a "monthly form" to sum up how much they worked that week. One of the aforementioned drop-down lists have them choose between three categories of work, M, N and B.

I have to make it so that in the monthly form, the results from the daily form segregate themselves into the different M, N and B tables in the monthly sheet. To make it more clear, on the daily sheet, there is just one huge table. For each row, they are to input what type of work they did, how long they worked, etc. On the monthly data table there are three different tables, one for M, one for N, and one for B. I want to have the entries from the daily spreadsheet to feed themselves into one of the three tables in the monthly spreadsheet depending on whether M, N or B was chosen.
