So I am building a java script that is used in conjunction of my C++ application for sending direct messages to users. the script does the work of building the request that i send. When i send a request i receive "Incorrect signature" or "can not authenticate you" Does anyone see something i am missing or am doing wrong? I am continuing to investigate. Thank you in advance

Javascript:

var nDate = new Date();
var epoch = nDate.getTime();
var nounce = "";

nounce = Base64.encode(epoch+randomString()); 

var Parameters =   [
   "oauth_consumerkey="+sConsumerKey,
   "oauth_nonce="+nounce,
   "oauth_signature_method=HMAC-SHA1",
   "oauth_timestamp="+epoch,
   "oauth_token="+sAccessToken,
   "oauth_version=1.0",
   "text="+sText,
   "user="+sUser];

var SortedParameters = Parameters.sort(); 
var joinParameters = SortedParameters.join("&");
var encodeParameters = escape(joinParameters);



signature_base_string = escape("POST&"+NormalizedURL+"&"+encodeParameters);

signature_key = sConsumerSecret+"&"+sAccessSecret;

signature = Base64.encode(hmacsha1(signature_base_string,signature_key));


sAuthHeader = "
  OAuth realm=, 
  oauth_nonce="+nounce+",
  oauth_timestamp="+epoch+",     
  oauth_consumer_key="+sConsumerKey+",
  oauth_signature_method=HMAC-SHA1, 
  oauth_version=1.0,
  oauth_signature="+signature+",
  oauth_token="+sAccessToken+",
  text="+sText;

goNVOut.Set("Header.Authorization: ", sAuthHeader);
