"Next Poll/Post" Function help?

[eluser]Unknown[/eluser]
Hey guys,

I really need some help which I think will be really easy for some of you - basically I want to create a function on my site to create a link to go to the net poll and the previous poll. This is my site, and the table the polls are in is called votings but I really have no idea what to do.

Can I get a bit of guidance as to a function that could create "previous poll" links and "next poll" links?

Thanks in advance.
