Dare to Complete this Complicated FORM

[admin]

IN THE NEED FOR HELP!!!

IT SEEMS THAT NOBODY is Successfull with this one

When I choose my values and ADD them to the Textarea, I can only ADD them once, i want to be able to ADD them twice, etc.

Is it possible to ADD values to a Textarea anywhere you click inside it?

<script>
function passText(dp1,dp2,dp3){var str = '<"' + dp1.options[dp1.selectedIndex].value + " " +
dp2.options[dp2.selectedIndex].value + " " + dp3.options [dp3.selectedIndex].value + '">';
document.displayform.itemsbox.value = str;}</script>
