Adding to multiplied values

All

I've been hacking away on a little time billing database and I've been having
difficulty adding to a calculated amount. This is what I am trying to get
to in an insert (for the column 'grandTotal'):

($compRate * $time) + $expenses

I've tried various combinations of quotes, double quotes, parentheses and
what have you, but I still get errors like:

ERROR:  operator is not unique: "unknown" + "unknown"
and
ERROR:  invalid input syntax for type numeric: "7.50 * 5"

I've been able to figure out hours times comp to produce a subtotal, but I
can't seem to pull in an additional amount to produce the grand total.

What's the syntax here?


thanks,

r

Can we see the exact PHP code stands for the execution of related query?


Regards.

Sure, and thanks. This query works, but I fail at tying in $totalExpenses
to create a $grandTotal. (pine is gonna butcher this...);

         $query = "INSERT INTO invoices2 (idate, iperiod, inum, ijobcode,
iaccount, icomp, itime, isub, create_time) VALUES('" . $invoiceDate . "',
'" . $billingPeriod . "', '" . $invoiceNumber . "', '" . $jobCode . "', '"
. $accountNumber . "', '" . $billingRate . "', '" . $totalHours . "', '" .
$billingRate * $totalHours . "', 'now()')";

Well, can we see the code that's failing? There's nothing we can tell you
about code that works.....(other than it would be a bit tidier not to do
your math inside a query....)
