multiple select box values

[jrthor2]

I have a multiple select box with contact names and phone numbers. When you select a name that has "Investors" in front of it, I want it to display all the Names and phone numbers, but only show the word Investors once. For example, I want it to look like this:

Invesors: Name Phone Number, Name2, Phone Number 2

Here is the code I am using to seperate the value by a comma:

<? foreach($contacts as $value) {
list ($id, $info) = split (",", $value);
echo "<input type=hidden name=contacts[] value=$id,$info>\n";
}?>

Then here is the code I am using to display the data:

<?
echo "Contacts:";
foreach($contacts as $value) {
list ($id, $info) = split (",", $value);
$info = str_replace("~", "&nbsp;", $info);
$inv = substr("$info", 0, 9);
//while ($inv == "Investors") {
// echo "<p>" . $info . ",&nbsp;";
//}
if ($inv == "Investors") {
echo "<p>" . $info . "&nbsp;or <a href=mailto:investor@riteaid.com>investor@riteaid.com</a></p>";
} else {
echo "<p>" . $info . "</p>";
}
}
?>

But this gives me the following result:

Investors: Name Phone Number
Investors: Name2 Phone Number

Any help would be greatly appreciated
