sleep not sleeping

[tommycahir1]

hi all i trying to put the cgi script to sleep for 60 seconds but it doesnt appear to work as it calls the save_graph function almost immediately..
any ideas on what i have done wrong..

my $index = 1;
while ($index <= $NoOfIf )
{
my $pid = fork();
die "Cannot fork: $!" unless defined($pid);
if ($pid == 0)
{
# Child proces
recieved_packets($now,$then,$index);
exit(0);
}
$index++;
}
my $graphxlabel = "Time";
my $graphylabel = "No. Of Packets Recieved";
my $graphtitle = "No. Of Packets Recieved On Interface No. ";
my $infile = "indata";
sleep(60);
save_graph($graphtitle,$graphxlabel,$graphylabel,$NoOfIf,$infile);
print_graph;

To explain the code above better would be the recieved packets creates a file possibly multiple files if there are more than one process. then the script should sleep for 60 seconds(due to save file trying to read files that werent created yet).then read these created files and save a graph image then print_graph displays these images to screen ..

I'm glad you're sorted tommy, can you pinpoint the changes that made a difference?

yea i got rid of the save_graph function and the file business and just copied and pasted the code into the two sent and recieved functions so that they generated the images without reading or writing to a file..
