hi ...

you have to loop through the nodes with the name 'CommID[]' and build a javascript array from it ... like in the following example:

[CODE=javascript]/**
* returns an array with the values of the checked checkboxes with name
* @param name name of the checkboxes
* @return new_arr array with checked-values
*/
function get_array_for_c heckboxes_with_ name(name) {
var new_arr = [];
var nodes = document.getEle mentsByName(nam e);

for (var i = 0, n; n = nodes[i]; i++) {
if (n.checked == true) {
new_arr.push(n. value);
}
}

return new_arr;
}[/CODE]
kind regards
