I had to set all test modes to false in order to have the transaction forwarded to the appropriate authorize.net server. I am still in test mode with authorize.net and am able to sumit tranactions without the card being charged. According to the techs at authorize,net the cart settings will be the same, for live or test mode, and will be set at there end. Here is what I have at coded in the WA-Globals.php It is working and all is good in the world.
$WAGLOBAL_Gateway = "2"; //Enter the appropriate value based on the above key. PayPal is specified by default.
$WAGLOBAL_Test_Mode = "false"; //Set to true if you are testing your shopping cart and do not want to send information to your payment gateway.
//Only complete the payment gateway options for the gateway you have selected to use in the $WAGLOBAL_Gateway setting.
$WAGLOBAL_Paypal_Sandbox = "false"; //Set to true if you wish to use the PayPal Sandbox for testing transactions.
$WAGLOBAL_Paypal_User = "";
$WAGLOBAL_Paypal_Password = "";
$WAGLOBAL_Paypal_Signature = "";
$WAGLOBAL_Authnet_Sandbox = "false"; //Set to true if you wish to use the Authorize.net Sandbox for testing transactions.
