I have a HTML page which includes a javascript file. So, this HTML page looks like this:

<P>
This is my Html.
</P>
<script language=JavaScript src=http://www.mywebsite.com/Javascript/Banner.js></script>

Banner.js includes the following, which is mostly a bunch of document.write to create some content on the page:

document.write("<script language=JavaScript src=http://www.mywebsite.com/Images/MarketingTool/Banner400x77.js></script>")
if ((nType==1) || (nType==2))
{
   alert("1")
}

What I am trying to resolve is to make nType variable visible in Banner.js but I can't because it is initialized in Banner400x77, which is an include .js file and it won't take effect until Banner.js is finished processing. Anyone would know how I can have nType variable visible from Banner400x77.js while I am still inside Banner.js?
