I am certain that this is child's play for most of you, but only having programmed in Perl and SQL (and it's been 3 years) I simply can't figure out how to make this happen: I have one column of discontinuous data in an Excel Spreadsheet. I need to select each cell in a continuous block of data and add the subtotal to the next empty cell. And repeat with each block of data down that column.

Thanks in advance for any help anyone can provide!
