How do I copy data to end tab and have it appear sorted?

The title should read "2nd tab" not "end tab....I don't know how to correct the title. SORRY.

Hello,
I'm trying to write a formula that automatically copies data from one tab to a specific range on the next tab, and appear in alphabetical order even though it wasn't that way on the first tab.
The data that I want copied is in the second column, but which gets copied depends on the info in the first column A. So in the first tab, it looks like this...

COL A COL B
1 nillusory
2 proliferate
3 zany
1 inexplicable
1 cinnamic
1 nonprofessorial
1 timber
4 engender
1 busiest

and in the second tab (say Group 1 tab), I need it to look like this (grp 1 only arranged alphabetically):

COL A
busiest
cinnamic
inexplicable
nillusory
nonprofessorial
timber

The first tab is going to be modified by other people, so I need for the second tab to adjust correctly as they put in new words, or delete them.

THANK YOU SO MUCH!

I've attached a little example file...

Try this...

Data Range

	A	B	C	D
1	------	------	------	------
2	1	nillusory		busiest
3	2	proliferate		cinnamic
4	3	zany		inexplicable
5	1	inexplicable		nillusory
6	1	cinnamic		nonprofessorial
7	1	nonprofessorial		timber
8	1	timber
9	4	engender
10	1	busiest

This array formula** entered in D2:

=IFERROR(INDEX(B$2:B$10,MATCH(SMALL(IF(A$2:A$10=1,COUNTIF(B$2:B$10,"<"&B$2:B$10)),ROWS(D$2:D2)),COUNTIF(B$2:B$10,"<"&B$2:B$10),0)),"")

** array formulas need to be entered using the key
combination of CTRL,SHIFT,ENTER (not just ENTER).
Hold down both the CTRL key and the SHIFT key
then hit ENTER.

Copy down until you get blanks.

You're welcome. Thanks for the feedback!
