Hi Jacob Sorry, my fault entirely. I wrote it in a hurry after copy/pasting your example. I didn't change the variable names properly or test it. I still haven't been able to test, but this should work better now. function compute_salestax ($Amount , $State) { $taxRate = array("CA" => 5 , "WA" => 7, "OR" => 8); return $Amount * $taxRate($State); } $payment = 1500; $locale = 'CA'; print "Tax on $amount in $locale is " . compute_salestax ($payment , $locale); -- Niel Archer -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
