Put text area contents into another text area depending on which item selected from combo box.

Please can anybody help?

I select items from a combobox menu which are written to a JTextArea (on customer order page).  After selecting, I select from a further combox box of table names (array 0-5), and depending on which one selected, I need the information to go to one of 6 text areas (array0-5) on the table page.

I am totally stuck.

My code:
