Adding Rows depending on user input

Hello All,

Sorry to change the requirments entirely but I think I made it a lot easier now.

I decided to start my program with the minimum number of rows into my table (dimensions = B68:G72). This would mean I would have to add rows depending on user input

There are 5 entries required from the user at cells F10:F14. If the user types anything for F11 (preferably use the ISTEXT(if true, add rows) function), then I want to add 3 rows to the table, and delete 3 rows (for formatting reasons) above row 104.

IF the user types in cells F11 + F12, then add 6 rows (always add 3 rows per every cell typed in) and delete 6 rows before row 104.

PS: It is not possible to fill F12 and leave F11 empty, The user will know to fill the cells in order and as soon as he/she sees a cell that shouldnt be filled then no need to fill the rest (F10-F14).

Your Help In this matter would be greatly appreciated.
