Problems with SDL_JoystickRumble()

Ii tried to use SDL_JoystickRumble() just to check if i could get rumbling to work with my gamepads. however, implementing the line SDL_JoystickRumble(gamepad1, 20, 20, 1000); just gave me an exception

Exception thrown at 0x776EE01E (ntdll.dll) in Win32Project2.exe: 0xC0000139: Entry Point Not Found.

and a pop up that says:
SDL_JoystickRumble entry point for procedure not found in library for dynamic linkers

But when i tried to delete that line again i still got the same exception with the same pop up. does anyone know why this happen even if i deleted the line and how i can fix it?
