Your code was very concise and an appreciated analysis of the problem.
I've coded a keyCode based keydown validator that handles the 3 cases
(numeric, decimal, currency) which is what i'll probably use- It's
definitely going to be server side validated, more of a helper in the UI.
It's in the final code thread, but I will take your comments onboard all the
same.
Thanks
