That would tell you that the syntax of the For command (in your context) is: For[i = 1, i < 11, i++,b[[i]]=i/10] Note that arrays are indexed using double square brackets, single ones are used for function arguments. Rather than struggle like this, why not take a short course on Mathematica. People here can only correct the odd problems you present, and I think if you learned how to write good-quality Mathematica code you would never look back! David Bailey dbaileyconsultancy.co.uk
