Answer 1

Check your following HTML LINE 7 (remove that line) and LINE 14.

there is a missed " " after "btn"onclick in LINE 14. a space.
from :
<button class="btn"onclick="shownum('1')"><strong>1</strong></button>
to :
<button class="btn" onclick="shownum('1')"><strong>1</strong></button>

and on your JS , last LINE add "}"

and everything run well..

have fun.
