Answer 1

<input> element at line 50 has its 'type' attribute set to 'text' not 'number'

Answer 2

Remove space between 'input' and '[type="number"]'

Answer 3

You have to recorrect the num variable..so that it will work and remove the comment tag
Then you have to declare num

Answer 4

I just did, still no change

Answer 5

Ooh thought I changed it
Thanks a lot
