I can't find a way to do a Quotient in a new column, like the example in the Table link.
Help with this table Table

Can someone advice?
FYI
I found a way to do it by column but not by row.
if (GridValueAt(CurrentRowIndex, currentcolumnindex-2, CurrentSummaryIndex)=0) then 0
Else
(GridValueAt(CurrentRowIndex, currentcolumnindex-1, CurrentSummaryIndex)/GridValueAt(CurrentRowIndex, currentcolumnindex-2, CurrentSummaryIndex)-1)*100
if I do this
if (GridValueAt(CurrentRowIndex-1 (or +1), currentcolumnindex, CurrentSummaryIndex)=0) then 0
it gives me an error : "Argument #1 of 'GridValueAt' is out of range"
If you have a better I will love to hear it.
Thanks,

Help with this table Table

Thanks for your help,
I have another problem.
I'm doing the Quotient between years.
I have 3 rows per item
2010
2011
2012

There are some items that was sold only in 2012 so when I do this formula below it gives me out of range..
how can I tell it to ignore (or devide by 1) if the row doesnt exist?

If 2012 <> 0 then

(
If year(Gridlabelat("TOD_Master_sheet_For_Sap_Crystal_Logistic;1.DocDate", currentrowindex)) = ({@CurDate})
and (GridValueAt (CurrentRowIndex, currentcolumnindex+2, CurrentSummaryIndex)) <> 0

then
(GridValueAt (CurrentRowIndex, currentcolumnindex+2, CurrentSummaryIndex)) /


(

if   year(Gridlabelat("TOD_Master_sheet_For_Sap_Crystal_Logistic;1.DocDate", currentrowindex)) = ({@2011})
and (GridValueAt (CurrentRowIndex, currentcolumnindex+2, CurrentSummaryIndex)) = 0
then

0
else

(GridValueAt (CurrentRowIndex-1, currentcolumnindex+2, CurrentSummaryIndex))
)

else (

If year(Gridlabelat("TOD_Master_sheet_For_Sap_Crystal_Logistic;1.DocDate", currentrowindex)) = ({@2011})
and (GridValueAt (CurrentRowIndex, currentcolumnindex+2, CurrentSummaryIndex)) <> 0

then
(GridValueAt (CurrentRowIndex-1, currentcolumnindex+2, CurrentSummaryIndex))
year(Gridlabelat("TOD_Master_sheet_For_Sap_Crystal_Logistic;1.DocDate", currentrowindex)) = ({@2010})

else 0
)

)
else 0

Yes but ISNULL dont work for me, because I'm taking the year from the label
year(Gridlabelat("TOD_Master_sheet_For_Sap_Crystal_Logistic;1.DocDate", currentrowindex))

I can't add ISNULL to that..

That's my problem... for some lines it doesn't exist.
How do I tell it to ignore or deide by something else if it does not exist?
