Good folks, I've had a good hunt through this website and it does appear to me what I've done is correct (it obviously isn't)!
I'm trying to pass multiple select items via cgi but I only seem to be passing the first entry. The html gets formatted correctly (I think) as 
<form action="post" name="RunForm">
<input id="env" type="hidden" name="env" value="PROD"/>
<select id="runs" name="runs" multiple="">
<option>2010-08-17 ----- 039733</option>
<option>2010-08-17 ----- 039753</option>
</select>
<p>
<input type="button" onclick="UntarFiles(env,runs)" value="Combine Fil
+es"/>
<input type="reset" value="Cancel" name="Cancel"/>
</p>
</form>

The Javascript called when they onclick is 
function UntarFiles() {
    if (document.RunForm.runs.selectedIndex==-1)
    {
            alert("Please make a selection from the list.");
        return false;
    }
    
      var env = document.getElementById("env").value;
      var runs = document.getElementById("runs").value;

    var url = "atlanta_combine_postscript.cgi?&env=" + escape(env) + "
+&runs=" + escape(runs); 
    
    request.open("GET", url, true);

    request.onreadystatechange = IssueAlert;

    request.send(null);
}

and in the called perl cgi program, to receive the parameters I have 
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);

my ( $env, @runs );
      
$env = param('env');
@runs = $query->param('runs');

[download]
However whilst what I have in the called perl program may be wrong - since I can see in the error log I'm getting the error "Can't call method "param" on an undefined value"

So the issue I have is that when I select multiple items, I can see that what it is trying to be passed is 

atlanta_combine_postscript.cgi?&env=PROD&runs=2010-08-17 ----- 039733

rather than

atlanta_combine_postscript.cgi?&env=PROD&runs=2010-08-17 ----- 0397332010-08-17 ----- 039753

(if indeed that is how I would expect to see multiple items passed in)?
So two questions:
Can anyone see what I've done wrong to only pick up one rather than all selected items
and
Is what I've done to initially receive the data (as an array) correct?
Any help greatly appreciated as ever. Cheers
Kev
