What do you mean by "simply doesn't work at all"?
Do you get errors? Does it redirect after you submit?
Do the repeated records show in the form correctly and just the update doesn't work? Do you have a URL where I can see the problem live?
Please describe your problem in detail instead of your personal opinions about the quaility of work I provide. If you were as precise about describing the problem as you are in bad-mouthing our team, it would be a more constructive approach to actually solving the problem.
