html - POST Method Form doesn't pass variables unless refreshing the page -

i have html form modified purchased theme.

the original theme utilizes php file execute form action.

however; due client's need, need carry on variables signup page later registration purpose.

here's problem. form works, if refresh page. when it's first time visiting website , input information in form, not carry on information after click submit. if refresh page, re-fill form , click submit information carry on no problem.

my question is, sound normal problem html form? best way of constructing form pass on variables designated page? here's current code:

<div class="contact-form">  		<!-- form -->  		<form id="contact-us" method="get" action="http://example.com/registration/country.asp">  			<div class="col-xs-12 animated" data-animation="fadein" data-animation-delay="300">                  <!-- first name -->  				<input type="text" name="fname" id="fname" required="required" class="form light" placeholder="first name" />                  <!-- last name -->  				<input type="text" name="lname" id="lname" required="required" class="form light" placeholder="last name" />  			<!-- email -->  					<input type="text" name="email" id="email" required="required" class="form light" placeholder="email " />                      			<!-- zipcode -->  					<input type="text" name="postalcode" id="postalcode" required="required" minlength="5" maxlength="5" class="form light" placeholder="zipcode" />                      			<!-- id -->  					<input type="text" name="enrollerid" id="enrollerid" required="required" minlength="7" maxlength="7" class="form light" placeholder="sponsor's id# "/>  					</div>  					<!-- bottom submit -->  					<div class="relative fullwidth col-xs-12">  					<!-- send button -->  					<button type="submit" id="submit" class="form-btn light">submit</button>  					</div>  					<!-- clear -->  					<div class="clear"></div>  				</form>  </div>
