how are you trying to create it. Creating a new workbook (open a new
excel file) or click on the new sheet tab?
before you fill anything (just formulas, no numbers added, no
calculations) try click in first row/cell Column at top-left hold down
shift key and scroll to bottom of cells used (bottom-right) then click
copy, next click on sheet tab (or the + next to sheet tab). now click in
first row/column cell.
now go to edit menu and choose paste. or if that doesn't work try Paste
special and choose what you want it to paste. You may have to change
headers and footer Manually. then click on the + next to sheet again
and repeat again until you have a Year's worth)
then once you go a years worth finished and working. then save as to
save as you wanted. then choose save as again and rename slightly and
this will be for next year, repeat again each your you need (in fact
save a Back up blank copy just that have one to copy from). You will
have to change dates accordingly as your creating.)
See if this works.
If you can't figure send a Blank sanitized version to me and I'll see if
I can do it for you then you can edit as needed and re-save. Just need
some basic headers and formula for the first sheet.
