Your right, and I have gotten it to work that way, but I wanted to see how it would be done if I was to use an array. I was trying to do something easy just so I could "see how it would be done" I guess you could say. Plus when I run the function, I want it to output the total price for all states in the array, and not have to call the function and pass it a state and amount for each state. Thanks for the reply.

Say using CA, WA, and OR, and setting there tax rates at, whatever, say 5%, 7%, and 8% respectively. I want a function I can pass the array of states, and tax rates to that will display the total amount (amount + tax) of say a $1500 purchase. I am trying to use a switch statement to accomplish this, but I think I may be in over my head trying to do this with what I have learned so far... Here is the code I have so far I get 0 every time I run it, try not to laugh... :-) Thanks guys. $State = array ("CA" , "WA" , "OR"); function compute_salestax ($Amount , $State)

            {

             switch ($State)

                    {

                     case "CA" :

                          $Rate = "1.05";

                          break;

                     case "WA" :

                          $Rate = "1.07";

                          break;

                     case "OR" :

                          $Rate = "1.08";

                          break;

                    }

                    
             global $Rate;

             $Truetax = ($Amount * $Rate);

             echo "$Truetax <br />";

            }

$Amount = 1500; compute_salestax($Amount , $State); Jacob Bergman Network Technician Pullman School District #267 (509) 432-4012 jbergman@psd267.wednet.edu
