How to redirect users to another page after the "Next" button?

Please find the following lines in cc.main.js file:

c.find( '.btContactNext' ).click(function() {
                    $( 'html, body' ).delay( 1000 ).animate({
                        scrollTop: ( $( this ).closest( '.btQuoteBooking' ).find( '.btTotalQuoteContactGroup' ).offset().top - 30 )
                    }, 400 );
                    
                    var contact_group = $( this ).closest( '.btQuoteBooking' ).find( '.btTotalQuoteContactGroup' );
                    
                    $( this ).closest( '.btQuoteBooking' ).find( '.btTotalQuoteContactGroup' ).addClass( 'btActive' );
                    $( this ).closest( '.btQuoteBooking' ).find( '.btQuoteBookingForm' ).removeClass( 'btActive' );
                });

and replace them with:

c.find( '.btContactNext' ).click(function() {
                    window.location = 'http://www.google.com';
                });

Please edit the url according to your needs.
