Hamburger Menu on mobile not working - VERY URGENT!

Hi there,

I am having an issue with my hamburger menu function not working on mobile. Ideally, I would like the navigation menu to be smaller on top and bottom than what it currently is... 

As well as the hamburger menu fire when clicked on. right now it is being cut off.

If anyone knows how to troubleshoot this with code please advise!

HELP IS GREATLY APPRECIATED & THANK YOU SO MUCH!

Currently, I have this code in place:

//Main Navigation Header-Navy//
#header { 
    position: sticky; 
    top: 55px; 
}
//Moblie Header// - Needs to be slimmer?//
@media only screen and (max-width: 640px) {
  .header {
    padding-top: 30px;
    padding-bottom:0px;
  }}
