I wasn't aware that "package" has a specific meaning in mathematica. Thanks for pointing that out David. I have posted my code on this link : http://rapidshare.com/files/258720906/ho-lee.nb Have taken it from a paper on Ho-Lee Model implementation by Markus Leippold and Zvi Wiener. The first few lines in the code do not form part of original code, its just my (uninformed and bad) effort towards solving the error which obviously didn't work at all... Coupla forums I went thru suggested that the error could be because of some simple error in use of brackets "[" / "{"/"(", but I haven't been able to put my finger on it, hence this post.

Programs are best built up a bit at a time. Assuming your program is reasonably short, why not post it all - someone will almost certainly fix it for you. You should certainly not need to execute Unprotect[List] - this is a very bad move! I would also avoid using Off until you know why you want it. In Mathematica, error messages do not stop the code running, so it is not essential to turn them off - better to leave them there as a reminder that something is still not right! Also, turning a message off, does not fix the problem! David Bailey http://www.dbaileyconsultancy.co.uk
