Hello Monks, regarding the following code 
my $PreMute = "Off";

Win32::GUI::Dialog(); #line 174

sub pre_mute_button_Click
{
    $PreMute = "xxx";
    if($PreMute eq "On")
    {
        $PreMute = "Off";
    }
    else
    {
        $PreMute = "On";
    }
}

When ever I press the pre_mute_button button I get this message "Argument "On" isn't numeric in subroutine entry at C:\guardian_service\guardian_service.pl line 174." What puzzles me is that this assignment (added for debug) $PreMute = "xxx"; causes no messages but the assignments within the if statement generate the message What am I doing wrong Regards Justin

PS Sorry if this is repeated, I thought I was previously logged on
