Who would solve this design issue for me... (firefox vs Explorer)

Firefox is not displaying our webpage the way it should be..
It makes the Flash header and a side flash picture show that we have in our website. The attached images show the exact issue. Using Dreamweaver cannot figure out the issue as in the preview of dreamweaver there is no gap...
I would apreciate your help and please feel free to suggest any improvements on our current site. (www dot hoteljuliani dot com)
Thanking you in advance

<< SOLUTION FOUND>>
Thanks B.V.E

 

Open the page in Dreamweaver, and you'll notice that the gap actually contains some code:

<p> 
    <script type="text/javascript">
        AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0','width','270','height','300','hspace','0','vspace','0','valign','top','src','./flash/left_animation','quality','high','bgcolor','#FFFFFF','pluginspage','http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash','movie','flash/left_animation' ); //end AC code
    </script>
</p>

HTML:

Changing, or simply removing the P tags, should solve your problem

 

Yes that is cause by html code

 

THANKS a million B.V.E
It was a <P> tag that had to be removed. works great now on both firefox & explorer!
