I am trying to total the number of line items per ID# in a particular column
within a spreadsheet, as pictured below. I do not want to create subtotal
rows, nor do I want to work with levels. I've tried various things with the
IF, SUMIF and COUNTIF functions, to no avail. I am fairly new to all this
and would greatly appreciate any and all suggestions.

Thanks!
