I want to load a worksheet with cell A10 containing a combo box
which will drag data from a SQL database.
The user will select from the list and then populate ajoining cells,
before tabbing down to the next line, Cell A11.
When they enter the new cell is it possible to apply a combo box to this cell and call the SQL routine automatically.

I don't really want to put the combo boxes in at the beginning, as I don't know how many rows the users may need.
