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?

The posted code is dependent on the while() loop executing. Have you checked that the query worked and returned a result resource (use an if(){} statement around the query) and have you checked if there were any rows in that result resource (use mysql_num_rows() )?
