I’m quite new to cs cart and i tryed to solve the problem reding the forum but 
my code :
I am suspicious of your banner’s name (flash/banner.swf) unless your banner is in a directory called ‘flash’. Try putting it in the root directory.
However try this code: (change background color from #FFFFFF to whatever yours is)
[COLOR=Black]
classid=“clsid:D27CDB6E-AE6D-11cf-96B8-444553540000”
codebase=“http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0”
id=“pear”
width=“540” height=“110”

type=“application/x-shockwave-flash”
pluginspage=“http://www.adobe.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash”
name=“banner”
width=“540” height=“110”
src=“flash/banner.swf”
bgcolor=“#FFFFFF”
quality=“high”
seamlesstabbing=“false”
