                     class="btn btn-primary justify-content-center">

Answer 1

Change type from button to submit:

<input type="button" value="Get Details" style="text-align:center;margin-right:500;"  
                     class="btn btn-primary justify-content-center">

to

<input type="submit" value="Get Details" style="text-align:center;margin-right:500;"  
                     class="btn btn-primary justify-content-center">
