Icon value counting

Can I count the value of smileies icons across a row. For example green is 4, yellow is 3, orange is 2, red is 1 and get a total value. Set up values in grade types but can't get anything to calculate.

Make sure you've assigned that grade type to the columns holding those icons.
You can do it in bulk from Tools > Columns > All > Edit > Grade type

Thanks fixed the problem. Now in one gradebook the calculation is showing up as a decimal .93 37/40, then another class the calculation is showing up as a as a 3 37/40 my grades are out of 4

Make sure the grade type of your calculation (double tap on header > grade type) is properly set.
