thanks for reply bro i try many time 


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

h1 counter hour1 is count 0 1 2 3 4 5 6 7 8 9

when condition 
  IF ( H1 = 10) THEN
                                H1 :=0;
                                HR_1 <=0;
                                H2 := H2 +1;

H2 = 1 will show us count from 0 to 1 so in broad show form 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

when i change H2 = 2 will show us count from 0 to 2 so in broad show form 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

so how make counter h2 count to 12 count? 0 1 2 3 4 5 6 7 8 9 10 11 12

or counter h2 count to 24 count? 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
