Adding column to view

hey friends,
i have a view which built last year. im wanting add to column to that.
but its giving error. What do you think is the reason?

in Toad, go to Main Menu -> Database -> Spool SQL -> Spool to screen.

Then perform the action again that gave the error. Then you can find the SQL that caused it.
