It sounds like the query is never performing since there is no data in the table to select. Try this...

change:

if ($totalonline > $numberoldhigh) {

to

if ( ($totalonline > $numberoldhigh) or ($numberoldhigh < 1) ) {

Check your highsessions table and see if any data is being entered.

Great! I finally got it to work.

I changed

if ($totalonline > $numberoldhigh) {

to

if ( ($totalonline > $numberoldhigh) or ($numberoldhigh < 1) ) {

But after that it still didn't work. Then I just went bold, went into the database and setted a
value of 0 in the "high" field. After I did that, it worked like a charm.

Thanks alot for helping me out. :D
