I'm Soo Lost! Trying To Append To A Table.

I have form linked to table 1. The form has a few control buttons that change certain fields. I am trying to make one of these controls also append a new record to table 2. Table 2 only contains three fields. One of them will have the ID number of the main record, the second field will have the date at the time the button was clicked, and the third will have the contents of a text field copied to it. I understand this is going to possibly create duplicates, but that's exactly what I want in this case.

My problem is; I don't have a dang clue what I'm doing!

I've tried the INSERT INTO stuff, and I tried to make an append query etc. but I just don't know what I'm doing because this is the first time i've ever had to do this.
