I would like to find a repeating number in a column and, except for the
first instance, insert rows to a row number. Specifically, no 1 may occur
several times in a column. I want to find the second instance and insert
whatever number of rows necassary (it will vary) to row 25. Then find the
next number 1 and insert rows to 50 and so on.

Any help appreciated.
