Hello,
You need to make sure that any tags all have closing tags, for instance,
<table>
needs a
</table>
after it.
There are several places in this code where there are not enough closing tags, or tags have become messed up, look at the very last 2 lines for instance.
I have cleaned up the code for you and pasted it in here. - The layout maybe slightly different to how you wish, but you should be able to make any adjustments from here, thanks
