Hi,
I'm not sure what the ö character in your onclick attributes are, but I think these need to be changed to regular o
Something like ...
From:
<table><tbody><tr><td><a önclick="First()">First</a></td></tr></tbody></table>
<table><tbody><tr><td><a önclick="Second()">Second</a></td></tr></tbody></table>
To:
<table><tbody><tr><td><div onclick="First();">First</div></td></tr></tbody></table>
<table><tbody><tr><td><div onclick="Second();">Second</div></td></tr></tbody></table>
I've also swapped out your archor tags for divs, as it's not good practise to use an anchor tag without an href value.
I also added the missing semi-colons after the function call in the onclick methods.
Hope it helps.
