Some help needed please

Hi there, I am hoping this hasn't been posted before, I am getting an error on the main indexpage of the forum

Parse error: syntax error, unexpected '<' in /home/sharece/public_html/forum/arcade.php(98) : eval()'d code on line 1

and also I am having trouble with the page, I am having to scroll from left to right for the whole page to fit on the screen

any help is appreciated.

Thanks

Still getting these problem's but also as I was checking it out fully today I noticed I have more errors, could it be because I havent taken all the files out of the FTP for v3arcade and just left them in?

I did try taking v3arcade out completly and got a database error so had no choice but to put it back in.

Any help is greatly appreciated.
