(data grid) is there a good workaround for obtaining other column values in FillInData for a Data Grid Table?

You have two options:
- change the script in the column behavior for the column you want to
display a sum.
- or define a default column behavior for the datagrid


If you choose the first option, change your script with a code like this:

on FillInData pData
   local tTheIndex

   put the dgIndex of me into tTheIndex
   put sumOfColumn(tTheIndex,"Col2","Col3") into pData
   set the text of the long id of me to pData

end FillInData

function sumOfColumn pTheIndex
   local tTheSum

   put 0 into tTheSum

   repeat with x = 2 to the paramcount
      add GetDataOfIndex(pTheIndex,param(x)) to tTheSum
   end repeat

   return tTheSum
end sumOfColumn


If you prefer the second solution, you're welcome to download and use
the code of the sample stack I proposed in my first reply ;)
