currency out of postgresql

I am trying to get two currency values from out of the database, add them together and print the to the screen. I am using the following code. $money = $myrow[6] + $myrow[7]; $formatted = sprintf("%01.2f", $money); printf ("<td align=\"center\">%01.2f</td></tr>\n", $formatted); $myrow[] is the array that I load the database records into. I can echo $myrow[6] & $myrow[7], which will show like $4.00 and $4000.00. But when I add them together the come out as 0 every time. The columns in the database are of type money. This is a postgresql database. Does any one see the errors of my ways? thanks, Rick Eicher II www.pbol.net
