Hi Keith,
Main issue is that there is nothing to distinguish the TextInput instances.
Plus the I iterative isn't working because it indeed will be that last number
of the loop it's not being used for anything else or assigned to anything.
To get around this, you could assign a different name to each of the input
boxes in the loop. So using your I iterative you could have: input.name =
"inputbox" + String(i);
Then in your event listener have:
Trace("input box changed = " + Event.currentTarget.name);
That should work ;)
Hope that helps.
Dave.
