An issue about change states
2. Color will be changed from blue to gray.
but after I tested it, the button, yes it will be disable, but not changing the color to gray.
I set a variable call attempt 01, original value = 0, when student click the retry quiz will + 1 .
The change states button trigger condition is when the attempt 01 value = 1, the retry button will disable and the color will change to gray.
However, only the disable function work properly but not the color, I am looking for a way to fix this issue.
