I am migrating a bookkeepping spreadsheet from Quattro v12 (c2001) to Excel 2007 and have hit a stone wall over relative 3-D references.
In this workbook each sheet holds data for one month, and this includes some lagging-12-month calculations -- that is, summing a range on a single cell for the preceding 12 sheets (including this one).
Unexpectedly, this formula:
=ISUM('201206:201305'!M6)
gives absolute references, even though I put in no dollar signs after the sheet names. This means it gives the wrong answer when copied to the next sheet to start a new month.
I can find no reference at all to converting the above formula from absolute to relative reference. Can anyone point me in the right direction?
Thanks,
yan
