I am about to create a Reservation webpage wherein if i click submit, it'll direct me to a file called REVIEW.HTML where all of my inputs are printed. I have here my RESERVATION.HTML code: 

 function tosubmit() {
     localStorage.clear();  
     var SelectCountry = document.getElementById("SelectCountry").value;
     localStorage.setItem("SelectCountry", SelectCountry.value);

     var SelectTime = document.getElementById("SelectTime").value;
     localStorage.setItem("SelectTime", SelectTime);

     var datepicker = document.getElementById("datepicker").value;
     localStorage.setItem("datepicker", datepicker);

     var Persons = document.getElementById("Persons").value;
     localStorage.setItem("Persons", Persons);

     return true;
}

<form>
    <div class="FrmName"><H4>Branch*</H4></div>
    <select id="SelectCountry">
        <option value="" selected='selected' disabled>Select Branch</option>
        <option value="Manggahan">Manggahan Branch</option>

You're storing .value of the .value string you've set the reference to.

var SelectCountry = document.getElementById("SelectCountry").value;
localStorage.setItem("SelectCountry", SelectCountry.value);

either change it to localStorage.setItem("SelectCountry",SelectCountry);

or var SelectCountry = document.getElementById("SelectCountry");

First of all, make sure to check if the browser supports local storage like so:

if(typeof(Storage)! == undefined)
{
    // Supported
}
else
{
   // Not Supported
}

Also, you have three operations on the button div and its child tag. I recommend that you put it all in one function, so your html would look like this:

<div class="button" onclick='tosubmit();'><a style="text-decoration:none;" font-color="Black"><center>Reserve Now!</center></a></div>

And then your OnSubmit function can handle the validation, local storage and navigation like so:

function tosubmit() {
    //if form is valid then 
        // Save data to local storage
        // navigate to next page
    // else 
        // Alert user that form is not valid
}
