Hi,
I cannot get my auto-number to work properly. The [Type of Book] can equal TB, BB, RB, or USB. I have used a similar formula before but I cannot get this one to auto-number like the others have and I am usnure what I have done incorrectly.
Thank you for any help.
=IF(AND(COUNTIFS([Row ID]:[Row ID], <[Row ID]@row, [Type of Book]:[Type of Book], =[Type of Book]@row) = 0, [Confirmed Book Number]@row = ""), LEFT([Type of Book]@row, FIND(" - ", [Type of Book]@row)) + COUNTIFS([Row ID]:[Row ID], <[Row ID]@row, [Type of Book]:[Type of Book]. <[Type of Book]@row), IF([Confirmed Book Number]@row <> "", [Confirmed Book Number]@row, LEFT([Type of Book]@row, FIND(" - ", [Type of Book]@row)) + , COUNTIFS([Row ID]:[Row ID], <[Row ID]@row, [Type of Book]:[Type of Book], =[Type of Book]@row)))
