[dave99]

I added and made sure I hade the same lines for the update and the generation of the float value

these are my photos although I expect for this to be a silly mistake in my code
thanks

The error is in the Quiz Script(Quiz.cs), not the timer. Can you show a full picture of the Quiz script?
