Hi,
The code seems okay on a first look, but here is one possible test. Change
<script>
function receiveCompletions(arr) {
document.f.comps.value = arr.join("\n");
}
</script>
to sth like this
<script>
function receiveCompletions(arr) {
alert(arr);
}
</script>
and see if you get any alerts with sth other than null. If you do then the
problem is with 'document.f.comps.value'. Otherwise receiveCompletions() is
not called at all. Is this specific to a particular browser?
