Geez, your right. I knew something was wrong with that.... Thanks

Now that that is working, how can I resolve the false positives? A small change to the code, shows that false positives are also counting as 'True': 
$thestring = "15,130,213";
$thecheck = "13";

if ($thestring =~ /$thecheck/) { print "$thecheck is in $thestring"; }
else { print "$thecheck is not in $thestring"; }

What would need to be changed here? The value in $thecheck should only be true if it is in $thestring, without variants.
