I am currently having trouble with my script outputing the scores when the user has scored a point by hitting the board on the plot with a ball. Any help will be greatly appreciated.

(script)

h=figure;
score = 0;
clf(h);
AxesH = axes('NextPlot','add');
while (1)
    
play = menu('Would you like to play?: ', 'Yes', 'No');
    switch play
        
        case (1)
            
        b = input('Please input angle value: ');
        
           if (b >= 0) && (b <=90) 
               
               [x,y] = HDTask1function_f(b);
                
                z = rand()*3.5;
                
                j = z+0.5;
                
                hndl2=plot([z j],[0 0],'LineWidth',5);
                
                hold on
                
                set(gca,'Xlim',[0 4])
                
                set(gca,'Ylim',[0 4])
                
                hndl=plot(x(1),y(1),'r.','MarkerSize',50);
                
                for ii=2:length(x)
                    
                    drawnow;
                    
                    set(hndl,'XData', x(ii), 'YData', y(ii));
                    
                    pause(0.0025);
                    
                    if y(ii:end) < 0
                        
                        y(ii:end) = 0;
                        
                        pause(0.5);
                        
                        if x(1,ii) > z && x(1,ii) < j
                            
                            score = score +1;
                            
                            fprintf('Your current score is: %4.2', num2str(score));
                            
                        end
                        
                        break
                    
                    end
                    
                end
                
           else
               
               disp('Invalid input. Please input an angle in the range of [0 - 90]');
           
           end
                      
        case(2)
            
            disp('Thankyou for visiting')
            
            break;
    
    end
    
end

(function)

function [x,y]=HDTask1function_f(a)
x0=0;
y0=1.8;
v0=4;
g=9.8;
t=0:0.01:5;
x=x0+v0*cos(a*(pi./180)).*t;
y=y0+v0*sin(a*(pi./180)).*t-(g.*t.^2)/2;
end
