Hi, I need some help to get this to work.
At first I had problems with the dynamic events not firing, now the problem is that the select from mySql returns data before it's updated.
If someone would please look at the code.. been rewriting this code like 10 times over the few weeks
(mainly because I had problems with the event of the dynamic controls, so I tried alot of different approaches)
Thanks!
