I created a small form witch is supposed to automatically calculate the price via onKeyUp=()
and in explorer all is working fine but in explorer the script goes exactly untill the following line.
document.getElementById(naam+"txt").value='';
after that the script quits no error it just stops.
I'll try to make the code as short as possible

I have also tried replacing getElementById with document.forms['name_of_form'].name_of_input.value
but I still get the same issue...
any idea is welcome!
normally you can check the result on http://joop.vazant.be/www/chiro/pastabasta.php
and the send option isn't written yet so feel free to test what you like :)
the best place to change something for testing is right after the second alert.
