[RESOLVED] add float figures

[gotornot]

Hi I am trying to add float figures together but for some reason its not working with the script below any ideas?

$ai = 0;
// Round upp all fees add them together
while ($feeitem = mysql_fetch_array($cartr))
		{
		$ai2 = $feeitem["fee"];
		$ai = $ai + $ai2;
		}

echo $ai;

All it does is output the 0

Figures are like 4.65 and 66.50

Any ideas?

Do you have all error-reporting turned on (including notices)?
