cc[[1]] is a list representing the first row of your table. Not that this is not a variable anymore. cc[[1]][[2]] is the second element of the returned value of the first row, so you are practically try to assign a value to something that is not a variable. simply use cc[[1,2]]=20. This will work for you. you can also use ReplacePart if you need cc=ReplacePart[cc,20,{1,2}] good luck yehuda On 9/15/06, mickey <micky at hotmail.com> wrote: > > Hi, > > I have a list of numbers, > cc(1,2)=20 > cc(1,3)=45 > > and so on.
