well, your supposition is wrong :) sorry. I definitely understand a race condition. what I don't understand is this: If a race condition could occur, even 1 time out of 1 hundred thousand iterations, isnt that enough to lock it? I could imagine, if I had a shopping cart system, that I would EVER want someone to know what my CC info was, however, if a race condition is even somewhat a potentiality then even the smallest chance of occurrence is too much of a risk
wouldn't you agree? btw, here is what I found about six months ago, and read to help understand this concept, its pretty helpful...there is also a java based graphic/animation simulation that explains this, and you can actually watch it happen...not sure of the url but here is the one I read.. http://www.cs.mtu.edu/~shene/NSF-3/e-Book/MUTEX/TM-example-philos-1.html ...tony Tony Weeg Senior Web Developer UnCertified Advanced ColdFusion Developer Information System Design Navtrak, Inc.

Its the same answer you'll get from Ray Camden, Simon Horwith, Christian Cantrell etc. Tony, I suspect that you may not understand exactly what a "race condition" is in terms of locking records and/or shared scope variables and would recommend looking up record locking in more detail. I tried to find a decent article on this, but this : http://www.linuxfocus.org/English/September2001/article198.meta.shtml is the best I could find...
