Field visibile condition based on Array Filed


Please help me to define a field visible condition based on array value. say "Others". When any of the array line value selected the value "Others" anothe Text field need to be visible for providing the user to enter the value for others.

Keep in mind Array field contains multiple entries (list values) and only if the user choose the value "Others" then the other field say "Specify" should be visible.
