However, when I try to use the Gravatar API, I always receive a...
I am trying to figure out how to create an 'if' statement that uses a time value as a condition. For example: if (time <= 10:00) { score = 3; } else if (time <= 20:00) { score = 5; } else { score = 9; } I know that a string of "5:23" cannot be compared this way but I don't think I can just turn a string value l...
