Passing options between two selectboxes
23 Apr 2002 10:21:29 D Adema posted:
<font face='Tahoma'>Hello everyone,
The following script enables users to add selected options from a selectbox to another.
Also, it should be possible to delete options from the second selectbox.
But or some reason it won't. I can't figure out why.
Can someone help me?

selectedValues = new Array();
function isSelected(value)

for (i=0;i<selectedValues.length;i++) {
