Looking good.

After you get some sleep, you may want to check that you have the following lines of code in the file...
PHP Code:
$recorddate = vbdate($dateformat,$maxusers[1]);
$recordtime = vbdate($timeformat,$maxusers[1]);
I noticed that it's not showing the date for your "Most users ever online" part. I looked at my install file and I wasn't very clear about that part. I said to copy all lines between another one and the code above, but I guess I should have said to include those lines as well.

Just put that code above right before this code and it should work fine.
PHP Code:
$getbgrow=getrowcolor();
eval("\$loggedinusers = \"".gettemplate('index_online')."\";");
