Warning: Illegal string offset suddenly appearing!

Hi Freaks

I believe this is caused by changing from 5.3 to 5.3, but what I can't work out is what the problem actually is!

 

This is the code section that is giving the error:

specifically lines 106-9 & 113

 $bonusGROUPED[$row[1].$row[2].$row[3]] = $bonusGROUPED[$row[1].$row[2].$row[3]] + $row[4] + $row[5]; //grouped data with bonus chips
    $pointsGROUPED[$row[1].$row[2].$row[3]] = $pointsGROUPED[$row[1].$row[2].$row[3]] + $row[6]; //creates grouped data for each player with points
    $totalpointsGROUPED[$row[1].$row[2].$row[3]] = $totalpointsGROUPED[$row[1].$row[2].$row[3]] + $row[4] + $row[5] + $row[6];//creates grouped data for each player with points
    $playedGROUPED[$row[1].$row[2].$row[3]] = $playedGROUPED[$row[1].$row[2].$row[3]] +1; //creates grouped data for number of times played
    $GBPCPoints = $totalpointsGROUPED[$row[1].$row[2].$row[3]] * $average_by_venue[$row[3]] ; // calculates number of chips
    $CHIPS = ceil($GBPCPoints / 1) * 1; //rounds up chipstack to nearest 25        

$arrGROUPED[$row[1].$row[2].$row[3]] =  array(1 => $row[1], 2 => $row[2], 3 => $row[3], 4 => $bonusGROUPED[$row[1].$row[2].$row[3]], 5 =>$pointsGROUPED[$row[1].$row[2].$row[3]], 6 => $totalpointsGROUPED[$row[1].$row[2].$row[3]], 7 => $playedGROUPED[$row[1].$row[2].$row[3]], 8 =>$CHIPS); //creates new array combining all the above data

}

To be honest I don't fully understand the error, so perhaps an idiots walk through of potential causes could help me rather than examining the code!

 

Either way any help would be much appreciated.

Cheers
