### Excel Facts

Can you sort left to right?
To sort left-to-right, use the Sort dialog box. Click Options. Choose "Sort left to right"
I'm sure there is a simpler way, but try this formula:

=IF(ISTEXT(A1),1,IF(B2<>B1,A1+1,A1))

hi Ben, thanks you, it worked, but i have any other problem, in col.a1 the data is number e.g. 1 , not text..any idea?

How about this?

=IF(B1="Data","1",IF(B2<>B1,TEXT(A1+1,"?"),A1))

hi Ben, thanks..i was helped..
my last question, it's possible using "count/if" formula?????

Put formula in A2 (your data in B2 and down):

=IF(COUNTIF(\$B\$2:B2,B2)>1,A1,MAX(\$A\$1:A1)+1)

or

=IF(COUNTIF(\$B\$2:B2,B2)>1,A1,A1+1)
