How to use a tag within a coldfusion

Trying to convert a <cfif> statement into it's if script counterpart but it's body contains a <form> tag.

This is located within an onRequestStart method within my application.cfc file.

CF

<cfscript>
    if (!isdefined("session.username")) {
        include "TEMP_Head.cfm";
        </cfscript>
        <form action="index.cfm" method="Post">
                        <input type="submit" name="LogOutUser" value="Log Out">
                </form>
        <cfscript>
        include "TEMP_Foot.cfm";
    }
</cfscript>

I expected this to run but I get the error message:

The start tag must have a matching end tag. An explicit end tag can be provided by adding </cfscript>. If the body of the tag is empty, you can use the shortcut <cfscript .../>.
