Very good day, from Chile 
Can someone help me insert code for my case?
I would be very grateful since I find myself somewhat frustrated.
What I need is that every time someone updates a grade, the average item is updated.
I don’t want to count how many times the grades are entered in each input item, I just want to take the average between the 4 input rating items and have it updated every time the grade of an item is changed.
my database contains the following columns:
-average
-total add
-rating input1
-rating input2
-rating input3
-rating input4
Thank you very much in advance!
