Dropdown menu inside an dropdownmenu

hi,

I know i`m not so good in explaining these kind of things
But i try one more time.
The first file that i attached consist of table data 2 and table data 3, you can select from the dropdown menu data 2 or data 3. When you select data 3 it shows the information from sheet 2 from the data 3 table and when you select the data 2 it shows the information from sheet 2 from the data 2 table.

when i select the data 2 there are a table in it starting from F17 and ending to K23.
now i want to make a dropdown menu to cell D16 which would have options table b and table c. so when i have selected first from the cell B3 the data 2 then i could select from the cell D16 one of the listed tables(table c or table b) and by doing that the information in F17 to K23 would change according to selected table. Table b and table c can be in another sheet.

hopefully you get the idea now, i´m running out of words

You can forget the attachment number 2, it was just to show how the dropdown menu should work..
