For loops index

[rturus]

event = ["A","B","C","D"]


for x in range(4):
 
    maximum=(int(input("Enter the maximum points for the " + event[x]  + " event ")))
    if maximum<5 or maximum>50:
        
        x=x-1
        
        print("The score should be between 5 and 50")
        
        continue
    else:
        print("The maximum points for the " + event[x]  + " event is " ,maximum)
        print("\n----------------------------------------------")
       
        

If a user enter a number less than 5 or more than 50 the code should go back to loop but the index should not be incremented. I tried it but it seems x=x-1 has no effect on the increment of the index. Any idea or suggestion what I am doing wrong or what I can do differently?
Thanks.
