MD5 AuthorizeNetSIM.GenerateHash does not match $response->MD%_Hash

$api_login_id = AUTHORIZENET_API_LOGIN_ID;                                         <-- Authorize.net supplied login

The only thing I remember is that the MD5 setting on your account can be too large. And it will get truncate when authorize.net is generating the response->MD5_Hash

Thanks mine is 12 characters.

The MD5 that is sent in the original post is fine.  No errors.

I just can not get the generatehash function to provide the same value returned by AuthenicateSIM.

Any ideas how I can debug or test? 

I have copy N pasted my ID and MD5 setting from SandBox Account.     What else can I do.

The ResponseCode 99 Tool   is not appropriate.    I think it is for the sending to Authenticate Hash.

Thanks for your response  :-)

public function generateHash()
{
        $amount = ($this->amount ? $this->amount : "0.00");
        return strtoupper(md5($this->md5_setting . $this->api_login_id . $this->transaction_id . $amount));
}

 That the source, see if the transaction id and amount look ok.

That was it!!!!    

I changes

AuthorizeNewSIM.php

function generateHash()

               $amount = ($this->amount ? $this->amount : "0.00");                   //   Added this line

                return strtoupper(md5($this->md5_setting . $this->api_login_id . $this->transaction_id . $amount));

}

Maybe I deleted the line early in the process.   However it works.

I could never have found this without you.

Thanks.
