Hi, im trying to test my sage pay integration but to no avail.

Here is my code:

private function init_sagepay(){
    extract( static::$post );
    $settings = global_data::get_settings();
    $strConnectTo = "TTEST";
    $strVirtualDir = "VSPForm-Kit";
    $strYourSiteFQDN = global_data::get_web_root();  
    $strVSPVendorName = $settings->sagepay_vendor;
    $strEncryptionPassword = "z5p************";
    $strCurrency = static::$currency;
    $strVendorEMail = $settings->sagepay_email;
    $strTransactionType = "PAYMENT";

    $strProtocol = "2.23";
    if ( $strConnectTo == "LIVE" ) 
        $strPurchaseURL = "https://live.sagepay.com/gateway/service/vspform-register.vsp"; 
    elseif ( $strConnectTo == "TEST" )
        $strPurchaseURL = "https://test.sagepay.com/gateway/service/vspform-register.vsp";
    elseif( $strConnectTo == 'TTEST' )
        $strPurchaseURL = 'https://test.sagepay.com/Simulator/VSPServerGateway.asp?Service=VendorRegisterTx';

}

when using "TEST" im getting an error:

Status Detail:  5005 : The Vendor configuration is missing or invalid

when using "TTEST" im getting an error:

VPSProtocol=2.23
Status=INVALID
StatusDetail=The VendorTxCode you supplied is an invalid length.  VendorTxCodes should be between 1 to 40 characters long

I cannot seem to figure this out at all. If anyone has any ideas it would be greatfuly appreciated.

EDIT: $stuff echos out:
