How would I add a sprinting ability when Right Shift is held to the following code? Thanks for any help!

void InputController::injectKeyboardState(OIS::Keyboard* mKeyboard)
 {
 //camera
 float walk = 0,strafe = 0, up = 0, sprint = 0;
 
 if (mKeyboard->isKeyDown(OIS::KC_A))
 {
 strafe = -1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_D))
 {
 strafe = 1;
 }
 if (mKeyboard->isKeyDown(OIS::KC_W))
 {
 walk = -1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_S))
 {
 walk = 1;
 }
 if (mKeyboard->isKeyDown(OIS::KC_PGUP))
 {
 up = 1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_PGDOWN))
 {
 up = -1;
 }
 
 GST->GetCurrentCam()->UpdateLocation(walk, strafe, up);
 
 //player
 walk = 0, strafe = 0, sprint = 0;
 
 if (mKeyboard->isKeyDown(OIS::KC_UP))
 {
 walk = 1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_DOWN))
 {
 walk = -1;
 }
 if (mKeyboard->isKeyDown(OIS::KC_LEFT))
 { 
 strafe = 1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_RIGHT))
 {
 strafe = -1;
 }
 
 if (walk != 0 || strafe != 0)
 {
 Quaternion q = TPCAM->GetRotation().Inverse();
 Ogre::Vector3 send(walk,0,strafe);
 send = q * send;
 PLAYER->orderMove(send.x,send.z);
 }
 }

I tried this - but it didn't do anything. help please.

void InputController::injectKeyboardState(OIS::Keyboard* mKeyboard)
 {
 //camera
 float walk = 0,strafe = 0, up = 0, sprint = 0;
 
 if (mKeyboard->isKeyDown(OIS::KC_A))
 {
 strafe = -1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_D))
 {
 strafe = 1;
 }
 if (mKeyboard->isKeyDown(OIS::KC_W))
 {
 walk = -1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_S))
 {
 walk = 1;
 }
 if (mKeyboard->isKeyDown(OIS::KC_PGUP))
 {
 up = 1;
 }
 else if (mKeyboard->isKeyDown(OIS::KC_PGDOWN))
 {
 up = -1;
 }
 
 GST->GetCurrentCam()->UpdateLocation(walk, strafe, up);
 
 //player
 walk = 0, strafe = 0, sprint = 0;
 
 if (mKeyboard->isKeyDown(OIS::KC_UP))
 {
 if (mKeyboard->isKeyDown(OIS::KC_RSHIFT)) {
 sprint = 1;
 walk = sprint + 1;
 }
 else {walk = 1;}
 }
 else if (mKeyboard->isKeyDown(OIS::KC_DOWN))
 {
 if (mKeyboard->isKeyDown(OIS::KC_RSHIFT)) 
 {
 sprint = -1;
 walk = sprint -1;
 }
 else {walk = -1;}
 }
 if (mKeyboard->isKeyDown(OIS::KC_LEFT))
 {
 if (mKeyboard->isKeyDown(OIS::KC_RSHIFT)) {
 sprint = 1;
 strafe = sprint + 1;
 }
 else { strafe = 1;}
 }
 else if (mKeyboard->isKeyDown(OIS::KC_RIGHT))
 {
 if (mKeyboard->isKeyDown(OIS::KC_RSHIFT)) {
 sprint = -1;
 strafe = sprint -1;
 }
 else { strafe = -1; }
 }
 
 if (walk != 0 || strafe != 0)
 {
 Quaternion q = TPCAM->GetRotation().Inverse();
 Ogre::Vector3 send(walk,0,strafe);
 send = q * send;
 PLAYER->orderMove(send.x,send.z);
 }
 }

hmm, it's just not changing anything and I don't understand why.
