this text input has the same name, seeing as it comes after the
hidden field it will be submitted after it (in terms of the order
of the POST vars) too. the value of second incoming txtKeyValue
effectively overwrites the first - result is you always see an empty value.
after thought:
you can work around it with javascript or php (and possibly changing
'txtKeyValue' to 'txtKeyValue[]'), or just change the name of
one of the fields :-)
