Hi Shadedlight,
Separate the odd and even values into other tables.

Formula in A2 of the Odds table IF(ISODD(Table 1::C2),Table 1::C2,"")
Fill right and fill down.
Formula in A2 of the Evens table IF(ISEVEN(Table 1::C2),Table 1::C2,"")
Fill right and fill down.

Formula in C11 of Table 1 SUM(Odds::A2:B9)
Formula in C12 of Table 1 SUM(Evens::A2:B9)
You can move (Cut and Paste) the Odds and Evens tables to another Sheet.
If you use Footer rows, these formulas can refer to whole columns and will automatically adjust as you add more rows.
Please reply with questions.
Regards,
Ian.
