yes bro when i execution on broad show me hour counter from 00 to 99 but supposed work 00 to 24..... 


 IF ( H1 = 10) THEN
                                H1 :=0;
                                HR_1 <=0;
                                H2 := H2 +1;
                                
                                    IF ( H2 = 1 OR H1= 3 ) THEN
                                    H2 :=0;
                                    HR_2 <=0;
                                
                                END IF;

i change H2= 1 counter will show me counter 00 to 19 after that he rest again 


IF ( H2 = 1 ) THEN
                                    H2 :=0;
                                    HR_2 <=0;
                                
                                END IF;

i change H2= 2 counter will show me counter 00 to 29 after that he rest again 


IF ( H2 = 2 ) THEN
                                    H2 :=0;
                                    HR_2 <=0;
                                
                                END IF;

i change H2= 3 counter will show me counter 00 to 39 after that he rest again 


IF ( H2 = 3 ) THEN
                                    H2 :=0;
                                    HR_2 <=0;
                                
                                END IF;
